What means (CDMA) and (GSM) In Title of Rom? And I live in Brazil and my 3g is not working.Thanks
GSM is when it needs a SIM card for it to work, CDMA the SIM card is built in and is part of the device, and locked to a specific CDMA based network.
Have you tried changing the APN settings to match that of your carrier's?
Thanks, researched it, my carrier operates in the 850 MHz frequency, and the xperia play r800i not have this frequency.
I believe it can operate at the 850 mhz band, you just need to flash the correct baseband for it. I have no idea which one you need to flash on your phone though...

Anyone,
I have flashed a few roms and radios, and I love my phone.
Currently on latest Radio and LeeDroid 2.0a
My question is how can I tell if I am on the 850mhz NextG network or the standard 2100mhz 3G one?
I cant find anything in the phone that gives me this info.
Thanks
Daniel
Anyone?

You'll know when the 3G indicator in the status bar shows a H... meaning HSDPA.
What is the model number of your phone?
The only handset thats compatible with Telstra's Next G band is the A8183.
EDIT:
The ROM that I run on my Desire is this one:
http://www.t-mod.org/
It's a mod based on LeeDroid, but edited with necessary Telstra settings (apn, user agent, bookmarks, etc) -- but without the bloat
Yes I know the H icon, and yes I have a NextG phone. But nextg phones can still connect on 2100 band, which Telstra supports. And it is still HSDPA. I want to know if its connecting to 3g via 850 or 2100

Sorry you're right... Telstra handsets can still use the 2100 band.
From what I've been reading, you're network operator will change to "3Telstra" while using 2100.

I understand that the Telstra SIM cards have a preference for 850, then if unavailable 2100 then GSM, but other than looking at the operator id there's no easy way to tell which 3g band you are using.
With WinMo there used to be some stuff like HTC Field Test which was an app that provided engineering data about your device where you could see the carrier id (Telstra has a different carrier id to 3Telstra), but I'm not sure whether there is an Android equivalent.

I have looked in the menus at
Dialer : *#*#4636#*#* but nothing there
Telstra's 2100 network identifies itself as "3TELSTRA" (because it is half owned by 3) and Telstra's 850 network identifies itself as "Telstra Mobile" (or some such).
You can probably see this info in the lock screen and/or by pulling down the location bar. At least that's where I see it, but I'm using a cyanogenmod ROM. You can try forcing your phone onto one or the other under the wireless settings too.
Another way to tell is the MCC+MNC value, which you can view in the app "Network Info II". NextG (850) is 50501, 3Telstra (2100) is 50506.

woohoo I am on 850, that bodes well for my rural move!
Hello I live in New Zealand and we have a network here called Telecom XT which uses 3G freq: 850 & 2100 mhz.
Unfortunately all Motorola Defy sold here have their freq specified as: 3G Network: HSDPA 900 / 2100
I see in the development section there is a way to flash files to restore 3G coverage and one of the files has the 850 & 2100mhz that our Telecom XT network uses. Does this mean I can flash this file to enable those frequencies on this phone or does it mean that the Chinese versions of Defy have a different chip that supports the different frequency?
Hey,
Unless the Defy has a tri band WCDMA chip (which im pretty sure it doesn't) then you can't simply flash new radio firmware/RIL to enable frequencies.
If you want an XT compatible desire, your best bet is something from T-Mobile or more ideally Telstra Australia's NextG network, which is the same as XT. Mobicity for example sells NextG handsets which will work perfectly on XT.
If you have the 900mhz Defy i believe you are limited to Vodafone/2Degrees. Flashing these Radio/RIL fixes i think were because those with 850mhz handsets with issues running radios designed for 900mhz.
Just to confirm, Defy hardware can only do certain pairs of frequencies (e.g. as say mentioned on gsmarena.com) irrespective of what ROM is put on it ?
Is there anyway to find out (from model/serial number or other way) what hardware one has ? (for 3G frequency)
I'm pretty sure about mine, though I bought this Defy 2nd-hand and flashed it, so just wanted to be sure. (I flashed it with 900/2100 MHz ROM and it seems to work fine on T-Mobile 3G in London, UK. But wonder if there is a way to check - perhaps for another unit....)
Does it matter which firmware runs on which phone?
For example, running LT15i firmware on LT15a, or LT15a firmware on LT15i?
We know the radio ability is different on both phones, would that cause an issue?
Does using a wrong FW disable some radio abilities?

Yes it does matter. I think you can still use it because they have the same GSM bands.
BUT you cannot use 3G or HSPA if you use the wrong firmware. LT15i and LT15a have different 3G bands. Better check what your network provider is utilizing.
Or check the cellphone shops whether they sell the i type or the a type.
LT15i = UMTS HSPA 900 (Band VIII), 2100 (Band I)
LT15a = UMTS HSPA 800 (Band VI), 850 (Band V), 1900 (Band II),
2100 (Band I)
The UMTS bands are provided in the white paper of arc at SE developer world site.
i have a rogers branded LT15A and i flashed it with the generic firmware for the LT15i and 3g works fine. so far so good. when i used to have the x10 it ran fine with either version of software. i am not saying that there couldnt be an issue, just not one that i have had that i can directly attribute to using the international software instead of the north american one

I think firmware interchangeability is a one way deal for the LT15i and the LT15a, in the sense that you can flash an LT15i ROM on your LT15a device and still use 3G (I'm on rogers, and 3G works), but flashing a LT15a ROM onto a LT15i will not give you the 3G bands of the LT15a
I also flashed my Rogers LT15a with the LT15i 2.3.3 World Generic firmware
All running fine

Are you sure about this?
I just too, like the above two posters, flashed a world generic LT15i to LT15a and working fine on Rogers.
According to Wiki, rogers UMTS is operating on 850 and 1900 bands, both not supported by LT15i.
Is there something hidden in the drivers etc?

This is somewhat confusing. I used Xperia X8 before going to Xperia arc.
They mentioned that flashing the i or a version incorrectly will make 3G connection not possible (http://forum.xda-developers.com/showthread.php?t=875688)
I didn't even try to flash the a version before because my network provider is using the 2100 MHz band for UMTS (2100 frequency is present in the two versions)
I've checked Rogers wireless and noted that the network is indeed using 850/1900 bands for UMTS. Kinda weird that LT15i firmware is working.
It shouldn't matter what firmware you flash onto your phone.
Since v2.1, all firmwares have included the software portion of both "i" and "a" radios meaning you can run any firmware on any phone. (However, this DOESN'T mean that flashing an "i" firmware onto an "a" phone will give it "i"-frequency 3G when in an "i" coverage zone and vice versa. The hardware is what determines what 3G frequencies the phone is capable of handling and that is fixed.)
It's how people are already flashing the latest 2.3.3 update on North American arcs.
Make sure that you enter in your APN settings correctly once flashed. I've never had issue running any ROM and getting 3G data connectivity.

you beat me to it. you are correct
Do you think that this would work for a Neo (MT15i) phone too?
(would be a bless as f/w patches are more quickly available for the arc)
Just bought Xperia arc LT15A but when I check phone version it says LT15I. So i called the seller and im told that it was flashed with LT15I firmware thats why its showing as LT15I. Is that possible that it will show as LT15i? Box shows lt15a by the way and im a little confuse. Also what are the settings for APN I will be using it with Rogers network (data/mms). Thanks in advance.

Yep, flashing a LT15i firmware on a LT15a will change the name under "about". This is normal and should not affect the functionality of your phone. Rogers APN below:

Thanks pre I cant wait to add tweaks and apps to this phone.
I think I may know the answer to this, but before I throw the phone against the wall, I'll first check with you guys.
I have a Wildfire S running 2.2.3 with HTC Sense. The phone is SIM unlocked as it was bought outright, S-ON. It is the version incompatible with WCDMA 850MHz and I need it to work with WCDMA 850MHz (Australian Telstra NextG network).
Since S-OFF has not been achieved via software and for all intents and purposes the phone can't be rooted, is it possible to reflash the phone with a WCDMA 850MHz compatible ROM (I know such exists, for one Telstra branded ROM is compatible but I believe there is also a HTC debranded version)?
If yes, where would I find such ROM and where would I find instructions for that (I've downgraded HTC Desire HD before, I know I need a Goldcard). If not, thank you for your time and answer.
as far as i know, 850mhz band is hardware function. if your phone doesn't support it via hardware out of the box, no software is going to make that work on that band.

From what I've been able to gather, the pones are identical, the difference is just in the ROM and bands they've arbitrarily chosen to disable. There are other phones with similar restrictions in place and it can be fixed by software.
Thanks for posting, tho.

Stylen, if you've bought a non telstra phone, it will work work on the 2100 but not on the next g 850. Unless it has the required hardware then no amount of flashing will help.

Hey jsut wondering if anybody on this site is in the Ontario area and where they got their phone + when..
I cant seem to find an xperia play that works on local frequencies.
I recently received the one i ordered off Amazon. But it is not accepting my SIM, it cant even be unlocked cuz its an international phone..
Is there anything I can DO?
These are the frecuencies supported by Xperia Play in its GSM version:
GSM GPRS/EDGE 850, 900, 1800, 1900
UMTS HSPA 900, 2100 (Global except Americas)
UMTS HSPA 800, 850, 1900, 2100 (Americas)
Probably the UMTS frecuencies for America are supported by the R800a and the other ones by the R800i.
If you need a R800a and you have a R800i maybe you can flash a R800a rom to modify the supported frecuencies. Search this issue in the forum, you could find something about it.
Try flashing the R800a firmware and see if the phone will accept the card. Otherwise you are out of luck. Should have bought an R800a from rogers and simply unlock it.
I dont think this will work as an R800a can flash an R800i firmware and the frequencies still run on the R800a frequencies.
Edit: I bought my phone off someone from Kijiji for $200 a year and a half ago. It was locked to Rogers. I bought an unlock code for it and unlocked it. Then put in my Bell SIM card and input the Bell APN for data/MMS. Then I got my bootloader unlocked. So I am using a Rogers R800a, with a Bell SIM running MIUI v2.9.21 r1 from cosmic DAN.
