US 3G Diamond - What gives it 3G - Touch Diamond, MDA Compact IV ROM Development

I noticed an unlocked US 3G Diamond at Best Buy today. I'm sure this has been asked before, but I can't seem to find the answer.
What makes the US version work on AT&T with 3G over the imported version? I have not seen a radio upgrade that allows it yet. The handsets actually looked quite similar with the exception of the back and battery.
I'm just curious whether to pick up the new one in order to get 3G service, or is there a radio update expected?
Thanks to anyone that can shed some light on it for me.

I have a US 3G version and the freq. that at&t uses here has been enabled.

Sure, it would be the 850 and 1900 Bands. But there are Quad-Band radios available for the EU Diamond. I wonder if it's a question about the device not having specific hardware or just being able to enable those bands to work properly.

Sorry for my english
he American Diamond has quad band in GSM and only two band in HSDPA, The people here says that is a har problem not the radio, the people put the american radio (08) in European version and dont work.
The American version came with the 1340 mh battery and without the front camera. Carlos

I have a Touch Diamond I bought last week from new Egg, just like the ones from best buy. For some reason, I can pick up the 3G signal and it will hold on to it for just a second, then x..{disconnects}..then immediatly picks up Edge and then Hsdpa?
I get 25% Edge and 75% Hdspa. I guess if you read the box, it says it picks up a 3.5G internet Broadband Connection....Anything over 3.5mbps is Hsdpa.

I notcied that the US version had the 1350 mAh battery instead of the 900 mAh like the EU version. Was there any documentation on why they did this? Has anyone checked if putting the smaller battery and slimmer back on the US version causes any problems?
I also find it odd that HTC briefly listed the Diamond as a Quad-Band phone on their website, and have since changed it back to a Tri-Band phone.

I still have hope that our European Diamond will work with US 3G with somefirm ware flash or something

No, it will not.

US Touch Pro 2 Unlocked

Anyone know if they will be releasing an unlocked version for the US carriers? I would get the European version myself, as 3g isn't a big deal for me, but what gives me concern is the Wall charger doesn't include a US plug. Im sure this is a small deal considering i could proly just buy a standard HTC charger, but im just curious if they will be having an unlocked that will both include the US charger, and work on US 3g networks.
no word yet hua?
Why do you think the European model won't work on U.S. 3G networks?
European 3G I believe works on the 1900 MHz band (supported by the Touch Pro 2). U.S. 3G operates on the 850 MHz band (also supported by the Touch Pro 2). By technical standards, this should work fine in the U.S. on the 3G band.
As far as the charger goes, yes, that is a concern. But I don't doubt that somewhere in your house you've got a miniUSB charger lying around. If not, your local Wal-Mart/Target/Radio-Shack/Best Buy will have a million of them.

I have been on a number of blogs for the TP2 and they are seem to be in agreement that the European TP2 will only work over the EDGE network in US...
Personally, I am currently an iPhone user, but my wife is driving me crazy waiting for this US version!

Here is a good story on MSNBC.com on the various 3G standards. It is dated last Sept. but it is still good.
http://www.msnbc.msn.com/id/26511322/
uk/europe model will only work on edge in US. devicewire have done a detailed review on a europe model and could only get edge. to get 3g will need to wait for official model for that region.

Actually you have it awry. European 3G runs on 2100mhz not 1900. U.S 3G runs on 850/1900mhz.
If you go to HTC's site, the TP2 Euro model will do GSM/GPRS/EDGE on 1900mhz. SO if O.P imports a Euro version, he could use it on EDGE or he could just wait for the AT&T version. T-mobile USA's 3G runs on 1700mhz though.
T-mobile USA's 3G requires both 1700mhz and 2100mhz. Suppose to be hear around July 22nd...

Standard mini usb cables, yes and i also am aware i can also just charge the thing using the included USB cable. What im asking about is the WALL charger. If HTC uses thier standard USB-mini cable that is on a good chunk of their devices, including the HD/ Tilt/Diamond ect.. im sure finding a US charger wont be that hard.
Also, i was asking about an Unlocked US version, i do not intend to get one though the carrier as i dont want a modified version that they lock down. Nor do i care to wait till the fall when AT&T gets off their duffs to finally release it.
In any event, im just keeping my ear open and seeing what the grapevine heard about it.
Sorry guys. My bad.
I was confusing the specifications thinking that HTC would at least be smart enough to include full support for all markets. I was reading the Quad-Band GSM as support for HSPA/3G bands. I was totally bypassing the HSPA/WCDMA dual-band specification.
Chalk it up to a mix of wishful thinking and childish excitement. That does, however, kick the crap out of my week. Only HTC can bring me down this hard.
Well, I guess ATT got approved for theirs. Now the only question remains is, will their be an unlocked US version that supports 3g? or will we have to get the European version?
I'm in Taiwan for Computex and am so tempted to buy a touch pro 2 here. I would wait for the AT&T version but after seeing they changed the keyboard I want the HTC model. Only reason I haven't picked one up yet is because it only gets edge in the US on AT&T.
Does anyone know if the hardware cannot physically work on at&t's 3g bands or do we just have to wait for the at&t version to come out so the radio can be copied over or something. Thanks!

The hardware physically cannot handle it. The Euro/Asian model only supports 3G on the European and Asian bands which are completely different frequencies from the ones used in the U.S. It's definitely not just a matter of software.
And I think we all need to be clear that no one has any idea what the AT&T keyboard will actually look like. The promotional material we have all seen and discussed ad nauseum is a slap-together of the HTC mockup with AT&T's promotional verbage. Even the promotional bullet points list that the "HTC Fortress" has a 5 row keyboard while the mockup picture shows a 4 row keyboard. That picture, at this point, means pretty much nothing at all.
I see, Ill hold off then. Its kinda hard to justify ~$800 on a phone here anyways that doesn't have a warranty in the states. Thanks for the help!
Will the US Unlocked Version have the secondary VGA camera for video conferencing like the European one does?
What is the advantage of getting a carrier specific phone (AT&T or T-Mobile) as opposed to a US Unlocked phone outside of price?
I'm currently with Sprint and want to switch to a GSM provider.

the carrier phones usually come with some sort of branding (software: e.g. sprint tv application / hardware: different battery cover, different keyboard layout and so on)
This can either be an advantage or a disadvantage...

So basically what I was hoping for in terms of a 3G phone with a front facing camera won't happen this round.

Is there a version of this phone with 3G in the 850/1900 MHz AND 2100MHz frequencies?

I am a Kaiser (ATT Tilt / TyTn II) user who would like to upgrade to the Touch Pro II (Rhodium).
I know that the T-mobile version of this phone supports the 1700 & 2100 frequencies; while the European version of the phone supports the 900 & 2100 frequencies.
My Kaiser supports the 850/1900 AND 2100 Mhz frequencies, which means that I can travel all over the world and always find a 3G provider for my phone.
Does anybody know if there is a version of the Touch Pro II (Rhodium) that supports the same three 3G frequencies as my Kaiser; namely the 850/1900 MHz AND 2100MHz frequencies?
IMPORTANT: Please note that I am talking about the 3G (HSPA / WCDMA ) frequencies. I already know that the Rhodium is Quad band for on GSM/GPRS/EDGE; but for me to switch to this phone I MUST have triple band in the 3G bands; just like I have with the ATT Tilt right now.
Looking forward to your answers.
My guess would be the Tilt 2 (AT&T's version of the TP2) could have the bands like that. But I don't for sure...

Does ATT have the Tilt 2? For months I saw posts on the internet saying that it would come to ATT, but as far as I can tell (from ATT website) it was never made available.

TP2 - T-mobile US version does support the following bands - no 1700
I believe the T-mobile US version does:
Here is what I see in the phone "band menu" - No 1700 support..(I believe TMo US did not win this US frequency..)
GSM(900&1800) + UMTS(900&2100)
or
GSM(1900&850) + UMTS (1900&850)
or
UMTS(2100&800)
I can switch from "Auto" to GSM or WCMA..
Hope this helps you.
The T-Mo TP2 doesn't work on AT&T's 3G unfortunately.

No there is not currently a phone in the market that will enable you to use AT&T 3G.
Wait until AT&T releases their own version of the Touch Pro 2. (they will)
Or, if you don't care about 3G (you should care) then the European Version, T-Mobile version, Sprint version and Verizon versions will all work on AT&T's EDGE network.

Thanks for your reply and the reply of all others. So my own research confirms that there is no product out there yet that will support the same three bands as the HTC Kaiser (Tilt).
I am not in a rush at all. I was a Blackberry user for many years (had 3 blackberries) and I got fed up with Research in Motion because of their lack of operating system openness. That's when I switched to Windows Mobile...through a brand new ATT Tilt (Kaiser) which I purchased only a few months ago.
Its just that I am SO happy with my choice that I am thinking ahead to my next upgrade, since a bigger nad higher resolution screen, combined with faster processor, and more RAM would be ideal. But I am not planning to switch to the Rhodium anytime soon.
I will first wait for ATT to launch it at full price, then for people to start selling new units on Ebay, for competition to get intense, and prices to come down..and for xda-developers to really get active on that unit; then I will switch. So I am thinking that for all those things to happen I will wait about 6 to 12 months after launch date of the ATT model (which is the one I would need to get in order to gain the trully global flexibility) to switch over to that unit.
Thanks again for your responses.

Well the reason I stated that T-Mobile was using the 1700/2100 3G frequencies is because those are the one that they mention in the catalog of the SP2 that they make available through their website!
There is plenty of articles on the net which say that T-Mobile chose a frequency which is not used by any other carrier in the world, and they refer to the 1700 frequency. Here are just a few:
http://gigaom.com/2008/09/23/4-things-you-need-to-know-about-t-mobile-3g/
"The T-Mobile 3G network may look like those in use by other global carriers, but it’s not. T-Mobile uses a radio frequency band (1700 MHz) for 3G connections that is unique in the world. The carrier claims it allows faster data speeds but the reality is it means that only phones specifically designed for the T-Mobile network will work at full speed"
http://en.wikipedia.org/wiki/T-Mobile
In September of 2008 T-Mobile began rolling out it's 3G network (operating on the 1700 MHz band)
The official T-Mobile website says:
https://support.t-mobile.com/doc/tm23715.xml;jsessionid=xhk4zMCQaMfhQJxqos?
What frequency does your 3G network support?
Our 3G network supports both the 1700MHz and 2100MHz frequencies.
Since the T-Mobile website says they support both 1700 and 2100, I wonder if a phone that supports the "850/1900 MHz AND 2100MHz" combination (such as the Tilt, and perhaps the Tilt 2) works with T-Mobile's 3G network?

Last Friday I found the HTC Touch Pro2 (US Version) at On The Go Solutions:

They told me it will be available in about 2 weeks. According to them it will run Windows Mobile 6.1 and not 6.5.
Hope this helps.
Too expensive!
Hope price go low in a few months...
All TP2 versions comes with 6.1 installed but MS announced a free update to 6.5 soon as they release it!

Yes, price is definitely going down and quickly. Don't be fooled into buying at such high prices. If you take a look at the T-Mobile model it is being sold on Ebay brand new, unopened for US $449; and that is only a few weeks after the product was released. I expect the same behavior with the ATT model, or even lower prices if it doesn't include a front camera...and has less memory (as some have speculated) than the other models.
I am going to wait 6 to 12 months to get mine, and I expect to be able to obtain a brand new one, without a contract for aproximately $300 within that time frame.
Yeah.. I know
I expect to buy it lower in less time

Let me get this straight - So TP2 is not a true "world phone"?

I'm a little green when it comes to 3G stuff, but please correct me if I am wrong...
Yes, you can put foreign SIM cards in US TP2's but not get 3G coverage in Europe. On the other hand from what I have read, European TP2's (even the unbranded ones) will not work with 3G is the US.
And if I am wrong... can someone please point me to a TP2 that will work on 3G networks in most of the world?
Or does one have to have two TP2's to enjoy 3G.. one for the US, and one for Europe, etc.?

Until someone hacks it
I can't remember where I read it. But someone said if you wanted 3G in Europe, better to get a Euro unbranded model.
So perhaps this is under the assumption that it isn't hacked... not sure.
Slightly, off-topic Q but rather than start a new thread.... once a HardSPL is out for both the CDMA and GSM TP2's... will they effectively be "equal" devoces?
I really would like to pick-up a TP2 in the next few days... I like the VZ unit, but it's CDMA and since I travel quite a bit, really prefer and need more of a GSM phone, but don't like the TMO as no 3.5mm jack.

The Verizon unit already has international GSM bands unlocked, AND international (2100MHz 3G). If you've been a Verizon customer for 60 days or more you can call them up and get an unlock code for free and use any SIM card in your phone so you can get a cheap prepaid SIM and not pay the high Verizon roaming costs. There's also a small (I'd say around 25%) chance that the NA 3G bands will be found/unlocked, but at this point who really knows if they are there or not.
Actually the Telus CDMA TP2 supports the European 3G bands but not the American ones becuase technically you will be using it in North America on CDMA and outside America on GSM. So its the other way around
It seems that if you have the Sprint TP2 that it won't register at all on US GSM networks, but comes unlocked by default.
On Verizon (which I have) a simple phone call to support they'll give you the unlock code and you're good to go. I use an Orange (UK) Sim in mine just fine in the US and others in other forums have reported that using US SIM's from TMobile/AT&T work fine also in the US.

I have an unbranded HTC factory TP2, and it works in 3G mode anywhere I take it that has the 3G network... and I travel all over the US/Caribbean and back to EU/UK. Have not found one spot it hasn't worked (inlcduing some of the very obscure Carib countries), and I like the fact that it automatically picks up HS when within range without having to change any settings.
Just have to make sure that your provider gives you a 3G SIM (most of them are these days) and that you have the 3G service enabled on your account in the respective country.
Many people say they can't pick it up yet don't have it on their account, or think that their EU provider will automatically provide it as part of the roaming service... which is not a good assumption to make.

3G in North America? I doubt that. The phone does not support North American 3G bands. Are you sure it was 3G in North America??
Man, this is all confusing... I swear somebody has to come up with an HTML table of what phones work with what and where and stickify it.
Can people just put this to bed already!!!
The Sprint (North America) TP2 is suppossed to be used on CDMA in the US and GSM worldwide, hence the GSM radio is unlocked for outside America GSM use. This is how it comes default. If that is so hard to grasp, then there is no hope for some, sadly.
As for the title, the TP2 is a world phone, it works in the US (and North Ameria) on CDMA and elsewhere unlocked on GSM. That to me is the true definition of a World phone from a U.S CDMA perspective (and especially moreso as this is the CDMA version).
To put it in perspective, a Sprint customer (in this case, moi) gets the best of CDMA in the U.S and when traveling to visit his sister in High Wycombe in the U.K (like i'll be doing this Autumm) gets to pop in a PAYG U.K sim in the same phone and use it while over there. This phone doesn't get any "worldlier" to me than this scenario!!
Is the O.P attempting to specifically define a dual mode CDMA/GSM-unlocked World phone as not world phone because it's locked by default from doing GSM in it's primary market which happens to be CDMA (and in this case Sprint)?
This is not rocket science folks, it really isn't.

Point taken. It's just that with that same Sprint phone (correct me if I am wrong), you can't travel to Canada pop in a Rogers SIM card and get Rogers 3G.
Wouldn't the phone want to swing towards it's CDMA cousin, Telus or Bell?

3G in North America? I doubt that. The phone does not support North American 3G bands. Are you sure it was 3G in North America??

AT&T 3G runs on 850/1900 GSM, the TP2 supports both of those bands, how would it not work with 3G on AT&T in the US?
T-Mobile runs 3G on 1700/2100 GSM bands, both of which aren't included on the TP2, as far as my research has lead me to believe.
Basically while it may be a quad band GSM phone, it is only a dual band 3G device. It comes in two flavours - UMTS 900+2100 or UMTS 1900+850
The 900/2100 version is far more common than 850/1900

It supports those bands for HSDPA CDMA not GSM 3G
Network 3G EVDO Rev A (800/1900 MHz), UMTS/HSPA (2100 MHz), GSM/ EDGE (850/900/1800/1900 MHz)
This is the Telus version btw

"it Depends"
The US CDMA phone operates in 3 modes.
1 CDMA Only
2 GSM Only
3 'Global' (whatever it can find).
If you have it in Global it will generally take the CDMA local carrier over anything else. However, not always. I've had mine switch to GSM for a bit then go back to CDMA. But mine is Verizon and unlocked so it works everywhere in the US and I also have a UK sim card in it. So I'm a little 'different'.
But, in any case, you can tell the phone which mode to use if you want. All upto you.

(verizon TP2)
here we go again... (tp2 3g na)
"I have an unbranded HTC factory TP2, and it works in 3G mode anywhere I take it that has the 3G network... and I travel all over the US/Caribbean and back to EU/UK. Have not found one spot it hasn't worked (inlcduing some of the very obscure Carib countries), and I like the fact that it automatically picks up HS when within range without having to change any settings."
So, maybe he's wrong. But either way...
You wanna know why this keeps coming up again and again?
(not because we're all dumb and thick headed, which we may very well be)
But,
Because we just have trouble imagining them hardware "band amplifier" hobbling the hardware when it's so much easier to do it somewhere in firmware.
We all know that the less you fiddle with the hardware for multi-region functionality the less you have to fiddle with the production line and fiddling with the production line is the Last Thing a manufacturer wants to do.
Someone even once said that there wasn't room in the Rhodium platform for quad band data support. But now we're expecting the tilt 2 to do just that.
So, all protestations aside, those of us who paid ~700 us clams for this beauty, and who like the kbd layout.
And who have like me (as quite the Early Adopter), forked out for an sx56, sx66, 8135, x7510((quad band data)
Just feel a leetle wee bit of a sense, dare I say it, of Entitlement for the TP2 to be enabled into a fully world wide phone.
So we keep hunting, and digging, and dreaming, and .... posting.....
well here is my two cents i have the original unlocked euro version of the tp2 and all i get in the us it edge. it is really impossible to get 3g in the US (2100) because this version of the phone literally does not have the attena for it. and so that you can see all the different types of tp2s and the technical and physical differences between them here is a link: http://pdadb.net/index.php?m=pdacom...&id3=1792&id4=1829&id5=1766&id6=1989&id7=1751

3g in the USA must be on the 1700 band then, as thats the only gsm band that the euro version doesn't support.
Euro version
GSM850, GSM900, GSM1800, GSM1900, UMTS900, UMTS2100
TMOUS version
GSM850, GSM900, GSM1800, GSM1900, UMTS1700, UMTS2100
Anyone know of a good site to order a prepaid SIM card? I plan on using my VZW TP2 in Spain and France. I was also wondering if I should or could disable data and use my TP2 with Garmin XT so I don't get nailed for data usage. Your thoughts would be appreciated...

Can I make my Touch Pro2 work with 3G in USA?

Hello
I have HTC Touch Pro2 international version, so it doesn't work with 3G in USA.
Is there any way to make it work?
P.S. I have AT&T SIM card.
Thanks
This question has been asked and answered several times already, but the short answer is no. ATT uses different bands for 3G than in Europe and Asia so the international version won't get 3G speeds. Unfortunately you are stuck with Edge speeds.
Thanks for replying
I noticed that old PPCs (HTC, Xperia, ...) support all HSDPA frequencies even international versions, but the new ones don't.
Why is that?

It really just depends on the specific phone. The US versions tend to support both US and International 3G versions, but usually not the other way around unfortunately. Things really got wacky when T-Mobile USA decided to rollout their 3G on an entirely different frequency (1700/2100) than ATT (850/1900), whereas the rest of the world uses straight 2100. (Note TMO USA uses one frequency for up and the other for down, so an international phone with just 2100 won't get full 3G on TMO USA either).
Usually manufacturers have slightly different versions of the phone for different bands (like the Xperia X1 has two different revs for different parts of the world).
If a manufacturer wanted to make an UBER-GSM phone, they would have to put a Quad-Band GSM chip and also support 850/1700/1900/2100 (Quad-band 3G), which I don't believe currently exists (yet) and may never...

Verizon TP2 on ATT?

I switched to ATT because my wife wanted an IPhone. I figured the Tilt2 was the same as the Touch Pro2 on Verzion. I knew about the stupid keyboard, but had not realized it was missing the 3.5mm headphone jack. This is a big issue since the adapter is crappy and loose and audio is very poor. I use it in the car and everytime I pick it up to change songs the audio drops out and pops...
Anyway.. The Verizon phone has a Quadband GSM radio and Dual Band CDMA.
I read many places it will work on ATT, but only on the Edge network not the 3G network. See this article: http://pocketnow.com/tech-news/verizon-wireless-cdma-touch-pro2-works-on-gsm-att-network
If i'm not mistaken ATT uses 1900mhz
The specs on the VZW TP2 say:
GSM Quad-band phone capable of global roaming (850/900/1800/1900 MHz)
CDMA dual band (1900/800 MHz)
UMTS European/Asian 3G (2100 MHz)
Does anyone know if this can be fixed to offer full 3G?
I would imagine you wouldn't want to keep the stock Verizon Rom.
Could you flash the latest energy Rom on a VZW TP2 and select ATT as your carrier?
I would also imagine flashing the latest GSM radio might be bad??
Does anyone have any thoughts on this?
I'd love to dump the stupid keyboard layout and lack of 3.5mm jack...

Verizon released a Verizon TP2 radio upgrade in their official 6.5 ROM. A cab to install that radio alone without the official rom is definitely on PPCgeeks, and I'd imagine it's floating around here somewhere too. I don't know what you mean by "the latest GSM radio", but stick to the radio upgrade Verizon offered and don't flash anything intended for a solo GSM version of the TP2.

Thats what I meant.. The solo ATT GSM Radio. I figured it would be bad. There are many warnings that say it would be bad, But until just now I have not seen the REASON it's "BAD".... Bad can be relative.
If I'm on VZW and I flash a GSM radio and loose my CDMA.. Yeah thats bad!
But If I'm taking my VZW phone to ATT and I lose my CDMA but gain 3G.. Thats not so bad.
If I just brick the device... Thats really bad.
From some other posts I just read.. I think it bricks the device..
So for now.. I'll stick with the Tilt2.
to use the the verizon tp2 on the att network you have to flash a gsm radio. its disabled because of fcc rules. you will loose cdma functionality. atts 3g network uses umts(wcdma) 1900 and the verizon tps has umts 2100 which is used everywhere except north america. you can find guides on how to convert a cdma touch pro 2 to a gsm one.
