Could someone answer a novice question for me? I'm kind of confused.
Can I get an (unlocked) HTC Desire originally from Alltel or US Cellular (CDMA) and convert it to a GSM phone (for T-mobile)? If so, is rooting required?
Thanks a lot.
No, different hardware.
You would have to find a suitable CDMA antenna, and even then it probably wouldn't work properly. Carrier is differentiated, for the most part, by the phones physical antenna. That's what dictates which carriers network the phone will work with.

Thanks. I think the CDMA version does not even have a SIM slot.
I just picked up the nexus lastnight, now i see roms saying gsm so im guessing there are 2 options, i thought verizon was cdma but this phone has a 4g lte sim in it so it is gsm correct?
Verizon and the soon-to-be-released Sprint version is CDMA/LTE.
Rest of World is GSM/UMTS
You want the ROM's in the CDMA section, unless you want to brick your new phone.
Thank you

Or flash it to Virgin Mobile,Cricket or Boost?
The Sprint Galaxy S3 works only in CDMA networks... Not GSM.
Yes, it can be flashed to Boost, Cricket, MetroPCS, Virgin Mobile.

Yeah someone definitively needs to post a tutorial i will donate $10 for tutorial.
Head over to usgalaxys3.com. The owner of that site has already posted instructions to flash it to Cricket.
I'm in no way affiliated with that site, just sharing where I saw the instructions.

The radio hardware matters, it has to be compatible with 1900 mhz Sprint PCS band. But the other things like GPU don't matter. lol

Virgin uses Sprint towers so band is the same.
Anyone know how to flash Sprint GS3 to Virgin? Or will Epic Touch method work with GS3?

Bottomline - You cannot use GSM phone on a CDMA network unless it is a global phone and supports both GSM and CDMA as well as the frequencies of the carrier you intend to use.
That is an obvious spam post. Please people, there are no exceptions... you CANNOT take a Sprint or Verizon phone and unlock it to be used on ANY service that is GSM or uses a SIM card. Period. The unlock sites will just take your money. World band phones will already be unlocked for use on European GSM networks most of the time so no unlock code is needed overseas.

You can flash it to another carrier though.
Not if the carrier is GSM or uses a SIM card. There is no possibility. Whatsoever. And unless you know a network level technician on verizon, you are limited to the smaller regional carriers and prepaid services to flash a Sprint phone. And vice versa for a Verizon phone. They will not connect a phone that does not already have its ESN already in its system.

Its common knowledge about gsm and cdma,if you dont know what these are then you have no business flashing carriers.
Sprint phones can be flashed to almost all prepaid carriers,overseas cdma is less common however there are ways out there to even flash cdma phone to their carriers.My father in Ukraine had his Epic 4g flashed to a carrier that uses sim cards,so there are ways even overseas.I think some overseas carriers use both cdma and gsm.
Ok ima try to keep it as short and simple as i can. I have a stock T-999 s3 tweaked to perfection running of Net-10 prepaid with the bring your own sim. Not only that I have it network unlocked so no matter what sim i place in weather its AT&T, t-Mobile, straight talk ect. i have service, each service i can critique to its best functions. Now heres my point. I also have a US Cellular galaxy S3 , rooted, and no matter what i do or try i cannot get this specific model to run a gsm provider via sim card. Im no wiz, but i get the idea, and my idea is to take this phone that is not supposed to operate on gsm carriers and make it operate. A recent example of success doing so was with my Droid Razr Maxx HD, i was able to successfully root the phone but as you all know verizon does not support us gsm carriers within the united states , or even on their network for that matter they block it. however after flashing a different modem, i am currently running t-mobile with great service! So any talk of "its impossible" i dont need, negitivity is not needed. i am fresh to this stuff but it fascinates me. cutting to the chase, what needs to be done to this sgs3 model #SCH-R530U to make it operate and function on a gsm carrier within the United states. Hacking Manipulating and tricking is all welcome that what were all about. Ive tried several things changing to global mode, gsm only,, faking gps positions to outside the u.s. and apn settings among countless hours beyond and im at a loss.. please im open to ideas and suggestions hopefully one day we make every model capable as nevery other
I believe the issue you are facing is because that particular S3 does not contain the necessary GSM radio chip needed to use those networks.
According to this (and its a wiki so it could be wrong):
http://en.m.wikipedia.org/wiki/Samsung_Galaxy_S_III
That S3 does not have any GSM bands for 2G or 3G.
However, once T-Mobile launches its 4G LTE on the AWS band, it should work...assuming the 4G network is both voice & data over LTE AWS.
The RAZR does work cause it does have the necessary 2G/3G GSM radio chip.

Simply put, the Verizon galaxy s3 is the only variant that has both CDMA and GSM bands. So if you wanted to do what you're saying, it would be most possible with the Verizon variant.
But for what you want to do, you'll need a world phone. And I believe the Verizon s3 is a world phone. Just gotta "hack" the GSM bands. Since they aren't active by default. But your T-Mobile att s3 will never work on CDMA. Also not lte will most likely not work on other carriers.

Just curious about this. There is a lot of talk about T-Mobile S3 running/not running LTE once it starts, but what about this setting on my T999?

"So I put my phone into airplane mode and threw it... worst transformer ever. -.-" -My friend
Hey guys. I have a question about the sprint gs3. I have a friend being deployed to Afghanistan and I'm trying to help him get connected while he is over there. He has a evo 4g lte and I was shocked to realize is only a CDMA and lte device.
I know the sg3 has the global radios on board but I'm wondering what the options are for switching radios for global use on other sim cards while running the latest and greatest ROMs.
Any help would be appreciated.

There is no SIM slot in the Sprint variant of the phone. You should have him go to the Sprint store and ask them what phones are available with SIM slots and whether they will unlock it for his use overseas. Other than that, may I suggest a non-contract phone for use while he's deployed, perhaps a rugged one.
