Normally in the UK and, I think Europe, they're GSM but in the US CDMA or GSM. I may be wrong but hopefully someone will come along and back me up or correct me.

Ok are all the roms currently out gsm or cdma? Or does it matter?

If you have a GSM Desire (if you have a SIM card) then go ahead and flash away pretty much anything you want. If you're CDMA then I'm really not too sure.

I know MIUI do a CDMA ROM on their US site. I posted a direct link to it the other day but can't remember where it is now. Here's a starting point though. Hope this helps.

Do you have sim-card on your phone? If you have it is an Gsm-phone. If not it is CDMA.
yeah i got a sim-card, so it's all about if i have a sim card or not? but can't my Touch Diamond be both CDMA and GSM?
sry that i ask so stupid questions, but im new to the Touch Diamond.

nope, it can't. You have gsm. Thats it..
They also make a cdma diamond, but it can't use GSM.
If you wanna know more about the difference between GSM and CDMA, you can visit this site:
http://www.wisegeek.com/what-is-the-difference-between-gsm-and-cdma.htm
For short, your phone is GSM, so you SHOULD NOT upgrade your Diamond with a CDMA rom.
let's see if i get this right, since i got a sim-card that i can use in any phone i want to and still have the other phone activated, it's not CDMA? or am i completely out and nothing near the real thing about CDMA? oO
CDMA is a usa 3g system running on 850 and 1800 net they dont use simcard in there phones it is build in so if u want to subcribe to a cdma network ( sprint a so on ] u need to actived the phone sim
gsm is an all over the world used system whit have an simcard
Quite simply, GSM and CDMA are two different types of networks. Likewise, the GSM and CDMA Diamonds are two different phones.
and what about european 3G/UMTS - with USIM ?

USA Incredible in UK/Europe?

Hi guys,
Seen reviews of the Incredible and absolutely love it.
Can anyone tell me if the North American version of the Incredible will work in the UK? I'm thinking about buying/importing one with my pay cheque next month but am scared that I may receive a phone that can't pick-up any signals here.
I'm pretty sure these are all the bands we use here in the UK.
HSPA/WCDMA: 900/2100 MHz
GSM: 850/900/1800/1900 MHz
Can anyone clarify?
It is Verizon which makes it CDMA not GSM.

Ok, I get that it's going to be CDMA only but is that a software issue or hardware? Basically would I be able to convert it myself to GSM?
Check on GSMarena.com. They say it has GSM frequencies for HTC incredbile.

But Verizon does not use sim cards so there is prob not a card slot on it.
I know it's an exciting phone but to overuse a wonderful line:

Sorry.
You won't be able to use this phone for any carrier other than Verizon. With the right ROM and radio hacks you could get it to run on another CDMA carrier. You would be better off grabbing whichever version of the nexus one is available for your frequencies and hoping that someone ports the Incredible ROM over to the Nexus. This seems like it is likely to happen in short order IMHO.
Recap:
Verizon only CDMA Radio software
No GSM or HSPA support
No Sim card or sim card slot of any kind

[Q] Verizon Nexus run on GSM network?

I'm getting ready to deploy, and I was curious if you can convert the Verizon Nexus to run on GSM/international networks. If yes, how?
sorry
there is no way my friend. i just got back from deployment. I was in the same boat as you. sell that g nex my friend, and get the gsm one. i found one by going on ebay, searching for guys selling one close to me and off to buy it locally so you're not waiting on shipping. or put on craigslists for a trade for the gsm version, u never know.
Yep, what he said was right - you can't convert it over. The Verizon one has a CDMA antenna and all the other networks require the GSM antenna (why couldn't they have both!! probably for this reason..). And even if the other networks used CDMA, they have to specifically accept your phone into their network (some kind of CDMA authentication thing, whereas GSM accepts everything it can talk to).
So flashing a GSM baseband to the CMDA phone will not work?
NO! Do not flash a GSM baseband on your nexus. The VZW nexus doesn't have any of the GSM radios or frequencies and wont work.
Unfortunately the GN only comes with either GSM or CMDA/LTE. It may be worth looking into getting a global phone that supports both CDMA and GSM.

As already stated, definitely never do this.

[CDMA] Question about GSM ROMs

I'm going to be upgrading my phone within a week or two. However, I plan on keeping my Play for gaming purposes. (Mostly emulators and a few other games.) Now my question is, since my Play won't be an active phone anymore, is it safe to flash GSM ROMs? Or will that affect other phone functionality? If data is the only thing that's lost with GSM ROMs then I should be fine right?
EDIT: Woops wrong section, meant to post this in Q and A. Sorry about that! "^_^
I'm about to buy a xperia play as a gaming device, and the cdma versions are much cheaper, so I have the same question. If it's unlocked for GSM, can we pop a sim and use it as a GSM phone with the GSM rom?
Actually, your question isn't the same as mine. And to answer your question, the answer is no. CDMA devices are built to work with CDMA frequencies. You cannot get a GSM SIM and place it in your CDMA device. It just won't function.
You can flash a GSM ROM on a CDMA Phone. You just can't use any phone functions. ie messaging, calling etc.

Well, then I had 2 questions. 1 was your question, and then there was the other question. I thought Verizon had gsm in some of there phones, and you could unlock it for world use. It has a sim slot for some reason... The GSM roms are much better, so can we flash them on the CDMA R800x?

Alright thanks, once I get my new phone, I won't be able to do any of those things anyways.

Just as JayJ said, you can flash a GSM ROM to a CDMA device, but you'll lose your data functionality. I'm pretty sure Verizon is a CDMA frequency company. Though I may be wrong.

Checked GSM ARENA and your right. The xperia play CDMA is only a CDMA phone, unlike some phones(example htc trophy) I already have a phone, so this will be a nice wifi only device.

It is. Verizon, CDMA. AT&T Sprint and T-Mobile are GSM( not surre about Sprint. Something with an S is CDMA also.

Sprint is also CDMA.
To clear some stuff up. Yes, the R800x does have a sim slot. BUT it is not hooked up & our phones are hard coded for CDMA.

Will wifi still work if you flash a gsm rom to a cdma phone? I assume it will since wifi seems to be a kernel issue and I'd keep the cdma kernel but I'm afraid.
I also don't use the phone on a carrier network.

If you install a gsm kernel on a cdma rom you will get stuck in a bootloop. But if use a cdma kernel on a gsm rom you will get stuck with a blackscreen.

Silly Question About Unlocking GSM

Um
I have the vanilla GSM Nexus from Google and currently use it on T-Mobile. Since I cannot find a direct answer to this question, even though I think I know the answer...I want to ask anyway, in case there are others like me.
If I unlock my GSM Nexus, does that mean I can put my Verizon sim card in my phone and have it work or is there a significant hardware difference between the Verizon version and the Google Nexus version?
Thanks -- Be gentle with your replies.

No you cannot. The main reason is the fact that GSM version only has radio that is capable of GSM and HSPA+. Verizon radio is capable of CDMA and LTE. Whatever you do to the software, if the hardware isn't right, there's no way.
Also may I ask you what you mean by unlocking? Do you mean unlocking the bootloader? If so, that has nothing to do the radio.
Hope that answers your question

Yep...that nailed it. Thank-you!
I just want to make sure I am not crazy in how I interpret some of the posts I have read.
I am perfectly happy sticking with T-Mobile. I will just let my Verizon contract run out, then they can suck it.

The GSM Galaxy Nexus is SIM unlocked out of the box. It will work on any GSM network, but no, it will not work on Verizon because they are CDMA and LTE.
Remember that when people talk about "unlocking" here, they're usually referring to the bootloader, not the SIM card. Unlocking the bootloader has nothing to do with the network it runs on, but instead has to do with putting ROMs on your device.
