A question came up on the us forum for Defy about the different software builds until finally a Moto-mod came in with this. It's intriguing in that apparently the Defy has all band capability, but the software build limits the choice. Here's the quote:
"Each Blur Version for the Defy is all Carrier and Regional Specific like for instance For US T-Mobile Customers its 3.6.19.0 however for UK T-Mobile Users I think the latest version is 2.51 Other parts of europe are using 2.34 without MotoBlur and so on and so fourth, the main difference is Carrier installed apps and the confusing part, from what i've expierenced with the phone, Its the first phone i've ever seen with a software controlled universal radio supporting all bands, however its software tells it which band to use, for instance if you 2.21 and 2.51 UK versions are using UMTS 900/2100 where US's 3.6.190 is using AWS 1700/2100. there are ways if you look to obtain version 2.51.1 however this isn't the place to look on instructions on how to do it because its against the forum rules, is unsupported and with 2.51 if for whatever reason you wanted to downgrade you couldn't unfortunatly."
WHAT.
Software defined radio?
If this is for real the hackers SHOULD REALLY HAVE A FIELD DAY with this phone.
It's a shame they're too busy with the Samsungs and HTCs of the world..
There's quite a difference between true software defined radio (most radios these days are sort of there, as they are most commonly some embedded chip with custom firmware but nothing like a Linux kernel) and being able to switch frequencies to be used

I'm not an expert, but the basic thrust of this was that all Defy phones are identical and capable of all frequencies, but the firmware defines which can be used. Therefore it seems -- to this novice mind -- that change the firmware change the phone.
The other, related issue is the frustration of some Euro phone owners who really know nothing about differences in 3G frequencies. buy a phone and presume they can use them in the US (as one can with an iPhone). Those of us who prowl these forums are basically smart enough to know that before you buy a phone we have to be sure we can actually use it -- but 90% of buyers buy a phone presuming they can.
Okay well can someone on the forum test this out? You'd need the ability to try and access both sets of frequencies.
Example: You're in Australia and you have a Defy from Telstra which you've also unlocked. Your stock firmware supports 850/AWS/2100. You should be able to get an 850 MHz signal from Telstra's NextG network. Now, if you put in an Optus SIM and visit an area with 900 MHz 3G coverage but not 2100, you'll find the phone drops to EDGE or gets no signal.
So at this point, take a nandroid backup, and flash a 900/2100 firmware or replace the radio files with ones from such a firmware. Now repeat the same test... does it successfully register on Optus at 900 MHz?

Radio issues...
Strictly on the band issue, I don't think they are that apart. A good radio would be able to handle it without being full SDR.
I agree partly on the point that these radios are somehow SDR for they do change the frequencie ranges by changing firmware.
A full SDR would be able to change even to CDMA or something else, not only the band!
If you want to challenge someone for doing something about it, ask for a full tri-band version of the Defy radio! (That I would ask for too!)
I intend to use my Defy originally 850/1900 over a 2100 network.
Well that's is my humble guess.

Interesting, as if you go into the INFO menu and select "set preferred network type" one choice (which it will not allow) is CDMA. But it's there.
Which version of the Defy is UMTS 850/1900? I thought there was only 850/1700/2100 and 900/2100.
Also, pretty much all Androids have CDMA as a listed option, not because they're compatible, but because it's a testing menu that was designed to be applicable to a wide variety of phones.

I am in Canada and one of our carriers Telus just released the TouchPro 2
telus is a CDMA carrier, however, released the device as a world phone, quad band GSM and UMTS 2100 3G.
I am new to the GSM world and would like to understand better.
Telus and another carrier, bell mobility are building a 3G+ network that they plan to fire up later this year, the CDMA network will stay for a while and HSPA+ will be an overlay network with no GSM support.
Telus and bell plan to use UMTS 850/1900 bands.
When a company like HTC makes a phone, are the UMTS radio's hardware or software?
Is it possible for a OEM working with a carrier to hide UMTS 850/1900 bands or install 850/1900 bands in a new ROM update, say Windows 6.5 ROM?
It does not make sense to me for OEM's to make multiple versions of same phone, I understand each carrier has cosmetic outer requests, I am thinking of the core inside build.
It would be nice to have both networks in case the initial network build out for HSPA+ has issues.
Help!!
UMTS Radio is hadrware.
GSM/WCDMA(or UMTS, if you will) basebands are all hardware as the last poster noted. However, at the request of a carrier, one of the radios in a dual mode CDMA/GSM device can be disabled(as is the case with the dual mode CDMA/GSM version of the Touch Pro2 headed to Sprint here in the US). It is also [theoretically] possible to re-enable the GSM radio in one of the dual mode versions of the Touch Pro2.
On a side note, I wish the CDMA carriers here in the US would transition to GSM technology. I know Verizon will be conducting LTE trials late this year and early next year so that's a plus. It would be nice to transition to LTE, as well, or at least HSPA+....
EDIT: Actually, many OEMs make multiple versions of the same model device. The Touch Pro2 has numerous variants for each carrier which will sell it.
Well, in this case it's a different build from other Pro2's as it has cdma and therefore a different processor.
As for what it is truly capable of I don't know. Carriers have blocked out hardware functionality through software in the past (i.e. certain famous cases of phones with GPS having to wait a long time before a ROM that would let them take advantage of the GPS).
So maybe it's possible. I don't know if it is in this specific case, someone more familiar with the specific hardware and stuff will probably have to weigh in for a definite conclusion.
Hope so though...
UMTS Bands
Wow,
Thank You for the prompt replies.
I think the Telus TouchPro 2 is the same build as Sprint with Telus customization.
I understand that the hardware radio must be present for UMTS 850/1900 to work.
I am not too concerned about the GSM radio(s), just the UMTS radio(s).
According to the spec, it only has 2100 UMTS band
If Telus and likely Sprint have disabled the radio, is it possible to find out if indead the radio would support UMTS 850/1900 and could a cooked ROM enable those above bands?
seems I responded more or less at the same time as jaekidd
anyways...
according to the msm7600 spec sheet it can have the following umts combinations:
2100
1900+850
2100+800
2100+1700+800
2100+1900+850
Now I personally have no idea how one could check to see what options the installed hardware has and whether they are blocking something.
no idea if a new ROM could unlock those frequencies should they be present or how easy it would be to make a ROM to unlock them (they might need a ROM for a device with those features unlocked on that chipset from which to rip the necessary files/drivers for all I know)
And for the record, I think it might be more appropriate to say that the Sprint version is the Telus version with Sprint custommization (after all, the Telus version has come out first), rather than the other way around
and for the record the msm7200 specs sheet says it is capable of the same combinations but personally I can only remember dual band hspa in HTC's phones (the msm7200a sheet doesn't mention the combinations, just the individual bands)

HTC FUZE (AT&T's Touch Pro) has 850, 1900, and 2100 and I assume AT&T's Touch Pro 2 will, too.
Didn't know that, just the question remians of when AT&T will get theirs out to market.
Does any body know if it is possible and if so how to enable the HSPA: 850/1900 band on a Global (GSM/CDMA) Version of the TP2.
It already has the HSPA: 2100 enabled... so maybe someone RF inclined could shed some light on this question.
Thanks
I dont believe it has the hardware to do it. It is not a software tweak.
That is why so many people waited for the ATT version to come out. There is an Australian version that works on one of the bands but not both.
Sorry to say that I think you are wrong about the Hardware reason...
Apparently the Pro2 has the chip installed, but it's locked down some how. That info has been floating around from an inside source at Telus. they say it actually has 850/1900/2100 UTMS bands but just got "locked" by Telus.
Also sites like Engaget has long posted some HTC FCC info proving that; http://www.engadget.com/2009/05/20/htc-passes-cdma-gsm-hybrid-touch-pro2-through-the-fcc/
Also The TP2 uses Qualcomm's MSM7600. The specs for that processor allow two major sets of radio interfaces, only one of which supports CDMA 800 and 1900. That major set has two variants that support HSPA: 2100+800 or 2100+1900+850.
So the question is; is there anyone with the proper knowledge that can tell what is onboard the TELUS TP2 and if it has infact the variant that supports the North American frequencies, how do we enable it?
Thanks for posting with FACTS and not Thoughts as this is the only way we will get a valid answer to this question.
Hmm this is definitely an interesting idea. I'd love to have the front facing camera of the Global Version, but I still need 850/1900 UMTS
850/1900 WCDMA on Global version
Gentlemen:
While the chipset has the various frequency capabilities, it is the tuning of the antannae that determines which frequencies are recieveable , ie, turned on, in the various versions. The AT&T version has a different tuning of the antannae than the global versions.
While theoretically possible, the anatanne is part of the main board and must be physically removed and replaced. I have not been able to find a universal antannae that could be resoldered to the board, if one was brave enough to give it a try.
there is software changes to the chipset controller required as well.
I think it is pretty impractical and likely impossible to do outside of have a new board installed with the properly tuned antannae to make it work. I have researched this for some time now, in an attempt to be able to use the EU versions here in NA. I travel internationally a lot, to Asia and EU, and need the 2100 band, so that has been my motivation.
There may be someone else out there who has different information, but this is what I have learned in digging through the available data for the past 3-4 years of various HTC devices and their variants.
Hope this helps,
MWS
I have a CDMA Rhodium (Sprint version) that is unlocked so I can use it on AT&T. I want to put Android on it, however when I have tried in the past it wouldn't work because the GSM version wouldn't work on my phone and the CDMA version can't use the GSM signal. Is there anyway to use Android on my phone in this situation? Thanks in advance!

force_cdma=0 in your startup.txt, should work.
You can't run both radios at the same time, but GSM-only should work for you.

I thought simply unlocking the phone didn't help in getting American GSM signals, because the phone is set up to only look for Worldwide GSM frequencies which are different from American? It has the capabilities to run American GSM signals, but I thought there needed to be further modification besides just unlocking the phone. I know the actual frequencies have to be flashed to the phone in WM, but I was unsure on whether these frequencies are built into the XDAndroid build?

Frequency support is in the radio itself - you can't flash the capability. If what you say is true, then he may not get 3G service, but he'll at least be able to make/receive calls and txts. Internet should work, but be painfully slow.
I'm not sure what frequencies the RHOD supports, but AFAIK it's a lot - Sprint and Verizon sell the TP2 as a 'world phone' - and usually phones branded with that moniker have a wide range of frequency support - again, built into the radio. Has nothing to do with the software running on the phone. If the frequency is supported in WinMo, it'll be supported in Android.

I agree with you that it is built into the radio. What I was saying is that simply unlocking the phone in Windows Mobile does not "make active" the American frequencies because the programming is such that Sprint and Verizon make sure the software explicitly either blocks or makes sure it can not use those frequencies.
It could be that XDandroid does not have those limitations in the builds and can use whatever frequency you want to. I don't know how much XDandroid depends on the settings etc... of windows mobile to run though. It could be you might have to get rid of that issue in WM before Android will properly be able to use AT&T frequencies. I don't know which is true, because I am not planning to try to use AT&T on my phone, thus I don't care to explore it! I was just bringing up that possibility just in case the guy puts force_cdma=0 and it still doesn't work for him.

No worries. If that's the case, I'd like to know if it works in WinMo. Because if it works in WinMo and not Android, then we're missing something in Android. AFAIK we're not missing anything that's at the core like that, but who knows.
i always thought you had to unlock (http://rhodium.htc-unlocks.com/) AND flash a custom rom for it to work on gsm att/t-mo usa. i guess if it works in winmo, theoretically it should work in android w/ force_cdma = 0. naturally you'd only get 2G data, but ehhhhhhh..
I'm assuming when you say to use the force_CDMA=0 in my startup.txt file, you mean for the CDMA version of Android, correct? Or should I use the GSM version?

In order to operate on the domestic gsm network, you will need to Security Unlock, then flash a patched radio, then use a T-Mobile or AT&T SIM card. You will only have Edge data and not 3G.

This may sound like a stupid question but here i go.
I live in Romania, and i use Orange Romania as my carrier. From what i could tell they use the 2100 3G and 3G+ band.
I have to choose between a Motorola Defy and an HTC Inspire 4G to buy, UNLOCKED, from e-bay.
But, from what i understand from members in the Inspire forum, the HTC Inspire will not work for me in Orange Romania, because it uses the 1900 3G band. Now i don't know what to believe. I called my carrier and they said that if i get the phone unlocked, even if it's an Inspire, it's likely to work in my network, 3G-wise i mean. What are the chances of this?
Also, since my network uses 3G 2100 and i buy a Defy from e-bay, made in the USA with Motoblur enabled, can i use that phone at FULL CAPACITY? Will my youtube videos and wi-fi hot-spot recognition work always? How about Motoblur. Does it work in Romania if i buy the phone from the US?
Thank you in advance.
EDIT:-----------------------------------
While you're contemplating on an answer. The Motorla Defy i have at hand to buy is this:
http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=280658487905&category=9355&_trksid=p5197.c0.m619
From what i read in the phone description: "WCDMA 850/1700/2100, GSM 850/900/1800/1900, HSDPA 7.2 Mbps (Category 7/8), EDGE Class 12, GPRS Class 12, HSUPA 2.0 Mbps"'
From what i read in my carrier's description: 900 MHz GSM/GPRS/EDGE/HSPA+ 2G, 3G - 2100 MHz UMTS/HSPA/HSPA+ 3G.
This basically means that if i buy the above-mentioned Motorola Defy, i can use it at 100% in Romania, right?
Should be fine.
USA phones nearly always have 2100 3G capabilities (besides their domestic frequencies, like 1700 for t-mo). But a 1900? That sounds like at&t usa. However, it may have more than just 1900. If people on your forum are saying the HTC won't work, they're probably smarter than whomever you spoke with at your carrier. But, again, I'm not sure about the HTC. If it is a usa phone it may have 2100 as well.
Everyone on the forum says Inspire is available only through AT&T and only supports 1900.
So if i buy the Defy above, can i run it in Romania on 3G without problems?
Sorry for the double post, but this needs it's own post.
The above Motorola Defy i'd like to buy is 2.1 Android and MotoBlur enabled. Can i use MotoBlur in Orange Romania? Also, what are my chances of updating to Froyo, since it is made in the US? Froyo is not available as a stand-alone update for Romanian users, but do i still have a chance to get it this way?
And what's the best program for rooting it? Should i do it after i update to Froyo or before?

The phone you linked to is an unlocked model. I did not see where it states which band it supports, but you said it's 900/2100 thereby making it the "typical" unlocked Defy. They are all made in China, BTW.
Your best bet is to get the phone, immediately root it, and install CM7 (instructions posted elsewhere). CM7 comes with an application called baseband switcher which will tell the phone which frequencies to use for the 3g signal. You may have to try a couple different locals/settings to get the optimum performance, but as long as your carrier is 2100 and the phone supports 2100, one of the settings should work.
What about Froyo and MotoBlur? Will i get to use those down here in this sh**y country if i buy that phone? The guy who's selling the phone is telling me i can indeed update to Froyo.
As for the bands, i'm not worrying, my carrier uses 2100, the phone uses 2100 so it shouldn't be a problem.
So basically what i want is to get that phone, update it to Android 2.2 then root it and use it like this. With Android 2.2 Stock and rooted. Would this be okay?

Hey don't worry about froyo. There are several froyo Sbf you can flash on your phone. You can use baseband switcher to change 3g frequency. MOTOBLUR should work.

Hi friends, these days buy a samsung nexus I9250 galaxy, but I wanted something:
1. few versions of the galaxy samsung nexus there?
2. There is a version that supports GSM networks lte? which is?
3. i9250 model supports HSPA + 21?
4. i9250 model that handles frequencies in HSPA +?
There are 2 versions.
1) CDMA/LTE on Verizon Wireless USA only. Model i515
2) GSM/HSPA+ (21mbps radio). Pentaband (works on any GSM carrier). Model i9250
And that's it! There are no GSM/LTE models.

For your reference so you can stop asking: http://www.phonearena.com/phones/Samsung-GALAXY-Nexus_id5595
I'm not sure, take expansys for example:
USA:
Network: HSPA+ 21Mbps/HSUPA 5.76Mbps 850/900/1900/1700/2100 / Quad-band GSM/GPRS/EDGE: 850/900/1800/1900 MHz / (Band frequency, HSPA availability, and data speed are operator dependent)
UK:
Network: HSPA/WCDMA Europe/Asia: 900/2100 MHz / HSPA+ 21Mbps/HSUPA 5.76Mbps / Quad-band GSM/GPRS/EDGE: 850/900/1800/1900 MHz / (Band frequency, HSPA availability, and data speed are operator dependent)

from here:

So maybe there 4 different variant, also there a SC-04D for Japan,
SHW-M420S and M420K for Korea.
somebody have to check it , also the nexus S have plenty of variants, so I see nothing new here, but just go for standard GT-I9250 as it's pentaband 3G that will work in any country , BTW I dunno if GT-I9250* go with other build thank "yakju", not that it will do anything with the frequencies as it's software, but if you think of it, with other devices there mostly 2 main variants, 1 for Europe, and 1 for Americas, sometime also for China, and other regions.

It doesn't matter what variation it is, a GSM phone will work on GSM networks and a LTE phone on all LTE networks. (unlocked, of course)
GSM and LTE have completely different frequencies so a GSM phone will not work on LTE networks and vice versa.
PS. HSDPA+ has nothing to do with the phone itself but if the network you are on provides you with it.

Its all just semantics and slightly different radio software. They are all the same. You can use ANY i9250 model on ANY GSM carrier in the world. Read my first post it gives you all the information you need in practicality.
The i9250 is regularly for sale from dozens of resellers. Just buy one ffs.
What did you mean by Its all just semantics and slightly different radio software?
you mean it's possible to disable some of the frequencies with flashing different radio? from what I learned here, software have nothing to do with the frequencies that device supports, only hardware (antennas) matters here. also the other variants, are made for specific operators, so a normal i9520 wins, as you not depend on Samsung or the operator for OTA updates, also I'm not sure if let say J variant get OTA with "yakju".

Not hardware radio, software radio. The different variants (yakju** models) have slightly different radio software for the regions they're originally sold in. All i9250 models support the same GSM frequencies.
These models aren't necessarily made for specific carriers but specific regions. Any i9250 can be flashed to yakju with images from Google if you prefer. You will receive OTAs either way, but may receive them slightly faster if you choose to flash to yakju.
Long story short, you shouldn't care. Just buy the cheapest one you can get, because if it doesn't come with yakju out of the box, it takes about ~5minutes to flash it to yakju and be the exact same (and no this doesn't require root or anything, you just unlock your bootloader and flash images, then it is completely stock).
So just to drive it home again: ANY i9250 you buy will work on ANY carrier in the world. The hardware is the same, and the software may be slightly different, but 100% changeable to your liking. Just buy the phone.
Ok, and I guess, lock the bootloader after?
I also buy it soon, and I also want to use "yakju" build, but dont want to root or unlock bootloader, but there is no way to flash "yakju" without unlock the bootloader?
*sigh*
Jesus christ what happened to the experimental Nexus spirit?
Why on earth even get this phone if you are afraid of touching it?
It's a phone designed to be ****ed with and still be bootable with code hosted outside it if you **** it up completely. It's virtually impossible to break.
How on earth can you even consider buying this phone if your main intention is not using what is what made for?
If you don't want all that, just get a regular phone, made for regular people, where you get your updates, regularly, through some really ****ty 3rd party "value-addon" software. Which only runs on 2 versions of Windows. And slowly.
Or just get your yakju/non-yakju phone and get the updates when you do, which will still be before everyone else.
Really.
You are putting to much into this. Either you want a moddable phone, and this one is it, or you are not a modder, and you should get something else.

That's quite a pompous rant. Shame you're so embarrassingly off the mark. The Nexus is a dev phone, because it is important to have a smoothly running device with the latest operating system out there for manufacturers and app developers. It contributes to the viability of the Android ecosystem (#1 reason the Nexus is made for). Hence the rapid OTA system on an incremental version basis. But you're full blown ego-crazy if you think Google released a phone just for you - the 0.001% that wants to mod. This is a mass market phone now (#2 reason it is made for). Most consumers buy it exactly so they don't have to root and install custom roms to stay up to date without the inherent bleeding-edge bugs that goes along with hacking. All Android phones are moddable. Why the hell wouldn't you have bought something with better specs if you were just going to mod it? You did it wrong. Sorry to break it to you, but Google made the GN without your specific hobby in mind.

You don't root. You do unlock the bootloader, but who cares! If you must have a locked bootloader, its just 1 extra command line entry to lock it again after you're done flashing to yakju.
Don't think you're understanding really. Unlocking the bootloader on a Nexus is not a big deal. It is literally 1 command line entry to unlock or lock. Like I said, flashing yakju takes literally 5 minutes.
I know that, but people here talking about the variants of it,
how can we be 100% sure, that for example M and J have the same hardware?
and only the radio software is different?!

You just know! Stop worrying FFS. I could hand you either one with flashed yakju firmware and you would never be able to tell the difference (even with regional software you wouldn't tell). No matter what, you'll get an i9250 that's what matters.
