But your Sprint CDMA can never be TMobile GSM (or AT&T GSM) for that matter, this is a hardware difference.

Sprint's touch pro 2 is a world phone, you just have to get it unlocked and flash the universal radio

[Q] Verizon G-Nex on AT&T?

Will the G-Nex from Verizon be able to fully utilize AT&T's network if it is rooted and a new radio and rom flashed to it? i.e. is it capable of jumping the CDMA/GSM divide with software updates?
Thanks,
Akh

No. It only has a CDMA radio, not GSM. Software can't change that.

I thought I had read somewhere that Samsung was dramatically changing the radio design in the GS2 and G-Nex, so I was hoping it might be possible.
Thanks

Nope, not at all possible.

one point twenty one jiggawatts!!!!!

I'm curious about this too. Because the Sim card/4G is GSM, if we were to go into phone settings and set it to "GSM ONLY" would it work?
This is more an issue of curiosity than anything.
I understand that the CDMA radio won't work on a GSM network.
Just curious is all.

No it definitely will not work in any way whatsoever unfortunately.

Yes LTE is a form of GSM but the GSM radio in to only works with Verizon LTE, nothing else

No. It won't work.

It has even been shown that Verizon and AT&T are using different bands for 4G.

Galaxy Nexus GSM vs. CDMA

What's the differences between the two, if any?
I've been contemplating whether or not I should get the GSM version or CDMA. Are there any major differences between the two?
Sent from the future.

If you're on sprint, you kind of need to change to Verizon if you want the CDMA version. CDMA also has LTE aka true 4G, so speed will probably be better. VZW also has further reaching 3G coverage than AT&T, generally. On top of this, in my experience VZW's customer service is great, but everyone's mileage varies there.
The GSM version is not "official" for the US - you will have to pay full retail price on one ($600-ish) and sign up with tmobile or att to use it. No carrier subsidy.
Without further information about you, it's hard to say anything more.

I think the op was asking about the hardware spec. CDMA version has bigger battery and twice the storage space.

Does this mean that the Verizon version will not work on at&t? Or have slower speeds?

thanks. I wasn't referring to carrier information, though. I meant as far as hardware and software.
Did android 4.1 come with the Verizon version as promised?

Yes, verizon version will not work on ATT.
In the US is very simple. Two types of radios: CDMA and GSM.
Verizon and Sprint use CDMA.
ATT and TMO use GSM.
The smaller carriers generally use either CDMA or GSM and piggy back off the larger carrier towers.
Hopefully android devices which have hardware and software capable of using both radios will arrive and it'll become less of an issue, but as of now, the galaxy nexus is either GSM or CDMA, but not both.
Hope that helps!

How about in the UK? Is there only one of these versions? And how do I find what version I have?

UK is gsm

Your CDMA version has a CDMA radio, a LTE radio, and antennas tuned to the correct LTE and CDMA frequencies used by Verizon.
The GSM version has a GSM radio with antenna turned to all common GSM frequencies.
The radios and antenna hardware are completely different in these versions and so by this fact the firmware (the software or flash able 'radio') is 100% different. Flashing the wrong one can cause all kinds of issues from not working until reflashing the correct ones yo bricking your radio (depending on how the firmware is flashed, size differences, etc.)
CDMA and GSM and LTE are all very different. LTE is based off GSM which is why you have a SIM card in LTE (though CDMA can have SIM cards if that is how the company set it up, which also is why without the SIM card you can't use your CDMA parts either).

Sure it is. Just like EDGE is "officially" 3G whenever carriers think it's in their marketing interest to say so. No one owns the term "3G" or "4G" so there's no such thing as "true" or "official". It is certainly marked performance advance over HSPA+, with real world LTE uplink speeds higher than HSPA downlink. It's at least as big of a jump from EDGE to UMTS (200kbps to 600kbps) was.
If you're referring to LTE Advanced, expect that technology to be labelled 5G when it hits the carriers. Why? Why the hell not? It's just a stupid marketing gimmick. Most consumers don't even know what the hell it means, with something like 70% of the population thinking that the iPhone 4/4S has 4G. Mo G's mo money.

Just to go along with what you are saying, the ITU changed it so that the current "4G" techs such as LTE, WIMAX, and HSPA+ are considered 4G.

[Q] Stupid Question abot GNEX from Korea

Im Active duty military so i end up where every they send me. I had to purchase a local phone since i will be in korea for the next year. I chose the Samsung Galaxy Nexus as my phone. i wanted to know if i can still root this phone and flash a custom rom with out messing up the phone.
The model Number is SHW-M420K.
Its running ISC 4.0.1.
The boot loader says the Board name: tuna Rev 9.
The base band is: M420KRKK7.
Kernel Version is: [email protected] #1.
Build Number ITL41F.M420KREK24.
Please Let me Know Thank You

This is not a stupid question.
The simple answer is that the M420K is the KT Telecom version of the HSPA+ Galaxy Nexus, internationally known as I9250 but has bigger battery. So, yes. You can do all of the above.

Almost the same question though it might be repetitive or stupid. I have that HSPA+(3G) version of KT Telecom GN coming a few days later. Is that the GSM GNex? That is, will all the applications, custom ROMs and firmwares for GSM version in XDA going to work with my phone? I checked out both forums for GSM and CDMA version since all Korean phones use CDMA network, but it seemed like CDMA forum here was all about LTE version serviced by Verizon.

Basically, the Korean Galaxy Nexus is not CDMA. It is GSM and works in Korea using the 3G WCDMA. You can confirm this by switching off the 3G in the Wireless Settings "Use only 2G networks" and you will see that you lose the phone signal and can't make any calls.

Yes.
Prepaid or temporary sim card is pretty hard to come by cheaply if you want data.

Yes. Forget prepaid sim if you want 3G data.
Getting set up with a phone in Korea is a real pain for expats.

[Q] ATT Version Usable with T-Mobile?

I am going to switch to T-Mobile in 2 months so was wondering if it will work with T-Mobile's HSPA + Network.

AFAIK It won't, but the frequenceies are listed on both carrier's sites so you can have a look at that.

No.
http://www.androidpolice.com/2011/0...nt-4g-hspa-phone-will-not-be-covered-by-both/

Couldn't we just flash the t-mobile radio like with the t-mobile sgs2 and the skyrocket from at&t?

It should be possible. Check out the specs of the two: http://www.gsmarena.com/compare.php3?idPhone1=4804&idPhone2=4803
This is EXACTLY the same as Tmobile S2 and ATT S2 LTE: http://www.gsmarena.com/compare.php3?idPhone1=4129&idPhone2=4303
Some awesome dev needs to do some radio hacking to make the two phones interchangeable as they did for the S2/S2 LTE.

that article is over a year old. there are many devices that work on both carriers via 4g. looking at the frequencies on att version it should work with a radio flash.

There's hope then

The CDMA and TDMA versions are different and not compatible. A sprint or Verizon model will not work on GSM networks due to the different protocols used. AFAIK no phone is universally portable amongst US carriers.

Verizon/Sprint/US Cellular phones are 100% different in terms of radio hardware and software.
It is possible the T-Mobile/AT&T ones will likely work together, but why? Also something to consider is the AT&T Note on T-Mobile gets HORRIBLE battery life.

You sure about this? Verizon model will have a sim card and has GSM support. Verizon will probably block T-Mobile and ATT with all of their GSM/devices.

The SIM card is for LTE. The only way to get 3G on a CDMA device would be through CDMA.

Not exactly true... After a "hack" to my VZW Moto Bionic and dropping in an ATT sim from a demo Galaxy Note, we got working H+ on the Bionic.
Even after hack, the Bionic doesn't appear to support T-Mobile's 1700mhz so I get EDGE only when I use the T-Mo SIM out of my Galaxy S2.
But I wont have a Verizon Galaxy S3 to play with to see how that works.

Interesting, have not heard of that one but I will take your word for it. Either way, most phones do not have AWS bands for T-Mobile unless they are T-Mobile phones.

Assuming the Verizon version has GSM 3G radios in it (what they call a "Global" phone) I don't see why even it could be flashed if someone could get the radio hacked.
For example, my current phone, the Droid 2 Global, normally runs on Verizon's CMDA bands. Being a global phone, it has GSM radios in it which can be activated if you get an unlock code from Verizon (not difficult).
Here's the catch- the baseband locks the phone so that it does not work on AT&T and T-Mobile's frequency bands! However, some clever hackers at TeamBlackHat were able to hack the baseband to allow it to work on US carriers as well.
tl;dr if the CDMA versions have GSM radios it should be feasible to make them work on AT&T and T-Mobile.

Does the S2 and S2 LTE (skyrocket) succumb to bad battery life like the note does when their networks are interchanged?
