what is the difference in radio version ? is there any difference between cdma radios and gsm radios ???
What radio would you suggest I use with Sprint ? And links to them ?
Kinda noob at all this .

cdma and gsm are two competing cellular standards. The two biggest differences between these standards are international compatibility, and how the networks handle activating phones. The rest of the world is pretty much gsm so you can't use cdma phones overseas. Plus cdma phones are activated by carrier whereas you can start using a gsm phone by simply putting a active sim card in it (granted the phone is sim-unlocked). plus checkout the thread below for more info on differences between the two:

And as far as radio stacks go, only gsm ones are available as of yet and list of those is in the wiki:

Tnx for the input ,
I understand the difference between CDMA and GSM , My question was about radios . So I guess no one with CDMA can change the radio huh ?

Is the HTC Touch Pro able to work on U.S 3G band , if not is there a radio patch that will activate the U.S band on the device. Please help.
This is a very hot topic on this forum but so far from what i've been able to see none of the radios have enabled 3G. This is not to say that 3G isn't supported by the hardware although its looking pretty grim. It appears that the ELITE team is working on this since they just released Hardspl

We shall see what happens, although the bands are available in the "band" settings tab so it MAY be a radio issue.
Bit early to know yet, as there is only one user here so far who has hold of an AT&T Fuze (RAPH11000) we dont have a huge ammount of detail yet.
Both the newer 1.02.25.31 and 1.02.25.19 radios seem to have similar protocols (same QCT_BOOT and HTC_BOOT), it would be good if any user could flash the (apparently) older 1.02.25.11 radio and see if it does anything?
I really wish i could help out on this 3G front but no 3G in my area...
I can help...

I have the 1.02.25.19 radio here in Chicago. I know I have good 3G coverage from my TyTN II that I had previously. But why would you think the OLDER radio (1.02.25.11) would have U.S. 3G? ...jus curious.

Its bundled with the AT&T ROM which is currently on the AT&T Fuze devices people are testing.
Higher radio version number doesnt necessarily mean a better one, as veterans of the Hermes will verify
The overseas Touch Pro cannot get 3G in the US. Just like the Diamond, the Touch Pro from overseas (RAPH100) does not have a WCDMA 850 radio.
Flash all the radios you guys want... it's not going to get you 3G on the 850 band. You'll have to wait for the US version/ATT Fuze if you're in the US and want 3G data.
Anyone know when AT&T sould release US version/ATT Fuze?

Until we have tested newer ROMs and radios that statement is pure speculation. MANY devices have had missing bands and etc...but have had them unlocked in ROM and Radio updates so it is too early to be writing off 3G support yet.
I have a TouchPro coming tomorrow. I called HTC today and (although I have about as much confidence in this as the paper I wrote this on) I was told by a lower level tech (I think he knew what I was talking about) that a "software" upgrade would allow for the European 3G enabled device to work in the US for 3G
... I sure hope so since I forked out the cash today
The Treo 750 didn't even start out 3G capable at all and was made 3G able with a ROM upgrade
Hoping
Hardware
Maybe a very stupid question, but what about openning up an eu version to see if the quad radio hardware is there? I would assume the radio chipset would be labeled and numbered so that we would know once and for all.

I thought about this but cracking open a 900 dollar device and completely voiding the warranty really isn't worth it. If someone can get schematic from HTC which i doubt we could see if the hardware is installed.

I believe there is an asian hardware version, this is what the HTC techs keep mentioning that might have the 850 3G radio.
I have a case into HTC support asking them to answer the question for me around if the radio is hardware capable of 3G in the US and explained what bands I was talking about and that it was in the software to enable those. I Posed the question as if I was unhappy that I was selecting these bands and it wasnt working to try to get an answer out of them will report back when I am answered one way or another.

Just so you know - I sent a similar email to them regarding the 850 band on the Diamond and I was sent a very nice response informing me that the phone I purchased was not intended for the US and did not have the hardware capability to be used on ATT in the US. Low and behold the xda developers made the 850 band work. Now HTC offers a rom upgrade opening the 850 band they said was not in phone. Unfortunately the response you get will not be the definitive answer.

I understand yours and others' reasons for not believing me or assuming it's speculation. All I can say is there will be a lot of effort put forth for no reason, just like with the DIAM100, only to confim that the hardware everyone is trying to unlock isn't even there. If the efforts put forth do nothing more than prove the above to be true, then at the very least people can rest more easily with full confirmation.
Hi,
I flush my VF magic with 2.22.19.23I and I think he has a problem with 3g networks (somehow)
anyway, can anyone pls provide a link with the 2.22.19.26I Radio version for Magic?
btw, why does Nandroid won't backup the radio image?
Thx

i mean, he uses 1700/2100 MHz and not the "regular" 900/1800
will it be ok to use this?
ups, you are absolutely true. I didn't even look at the bands, just focused in the platform.
Sorry for that huge mistake. I would feel really awful if i would have screwed your device by accident.

see now theres your biggest problem. every country besides the US and Canada uses the 900/2100 combination and technically the tmobile US UMTS band is more like 2050
First thing - no phone was harm
About the freq. - r u sure about the numbers? I got UK VF and it works in my country (Israel) w/o any problem (the issue with the 3G was apn settings only)
I think my carrier is 800/1900

The freq of T-Mobile in myTouch are the same as the Nokia 5800 that are sold here in israel

I've read that XOOM use the Radio chip Qualcomm MDM6600 ( the same of Iphone 4 ) and that is compatible with CDMA and also GSM network.
If it's true there's a way to set the actual CDMA Xoom for using GSM net with a cooked firmware ?
Not possible. Verizon's Xoom does not have GSM, only CDMA and LTE down the road.

The chip is a world capable but the radio with it is cdma so it can't work on GSM networks unlessbit has a GSM radio. The chip probably just makes it easier for moto to produce xooms without having buy separate parts when GSM version comes out.

Hmmm. Pretty sure that's wrong. The chip is the actual modem - it is what *modulates*/*demodulates* digital signals to/from the radio. The "radio" is merely a power transmitter/receiver; the modem is what controls what the radio signals mean. As long as the radio is tuned for the right frequencies, it should work.
So, is it possible or not? Has anyone tried it?
I'd just buy a data dongle and have the best of both. CDMA -> GSM has brick written all over it.
hello there
i`m from IL and i want to know if i can change the GSM bands to my location
as i saw a few post on that but iwm dont understan that
thank all
I think the gsm bands are for the network provider (tmo, att, verizon) you cant change hardware.
I assume you mean the data network bands not voice or 2G.
There are 2 physically different phones z710e (most of the world & TMobile US) & z710a (US AT&T). Look at the following and put in your country to check carrier compatibility.

The second post was for a completely different phone.
The first post (I had a quick scan and will look in more detail if I have time) didn't seem to address the issue you have.
As far as I know (happy for someone to shout me down) the HTC Sensation is NOT capable of universal frequencies, it is EITHER:
Z710a (2G GSM 850/900/1800/1900 ----- 3G HSDPA 850/1900) (US AT&T)
Z710e (2G GSM 850/900/1800/1900 ----- 3G HSDPA 900/1700/2100) (US T-Mobile)
That's fixed in the hardware of the phone and can't be changed. As you can see GSM is the same BUT the data side of things is where it gets different, you will always get EDGE as it's 2G.
The Baseband mentioned is flashed as part of the firmware.
The RIL (Radio Interface Layer) is the bit between the ROM and the radio. That will almost universally come with the ROM and will have a pre-requisite radio version that you have to flash separately.
Now if there is a way to change the 3G frequencies I'm sure there are many folks that would like to know how, it'd make the Sensation more universally available and hopefully cheaper in the 2nd hand market.
You haven't mentioned what your exact issue is, what are you trying to change and why ?
you answer me thank u and have a nice day

I was on the phone with HTC last night and according to the tech there the UMTS bands can be changed on the T-Mobile Sensation 4G, but this would require a custom rom. I am not sure if there are any roms out there that do this already.
Hey guys, i would like to buy an one s the next days but i have an important question, since the c2 [s3 processor] will be the only one sold in the future in some european/asian countries (not in mine, just s4 here):
whats with CDMA / GSM? i read that t-mobile us has gsm phones but does that mean that the one s is only sold in the gsm version?
i am just asking because i don't want a phone without "enough" custom roms in the future, because there will be some for the c2 version only and if there are a lot for cdma only it won't be much for a european s4 gsm version.
thanks!

CDMA and GSM are different ways of transmitting radio (cell phone) waves.
In the U.S., to my knowledge, only Verizon uses CDMA. All other carries use GSM and most international carriers also use GSM. If you buy the phone from T-Mobile US, you can only buy the GSM version. If you buy it from Verizon, you can only get the CDMA version (this assumes Verizon actually sold the One S). I'm not sure about international carriers, but I would expect that most operate the same way. It would not be smart for a carrier to build out both CDMA and GSM networks due to the expense involved.
No matter where you get it or which SoC it has, S3 or S4, it will be GSM.
Thanks for your answers but it is too late, no one s from tmobile left in Vienna, they say one month... but I'm sure then they will get only c2...

Verizon and Sprint are CDMA. T-Mobile and AT&T are GSM. By extension, Virgin and Boost are CDMA since they piggy back of off Sprint here. We also have regional carriers like MetroPCS and Cricket kthat are CDMA. IIRC, T-Mobile US phones are better than AT&T phones with international compatibility.
