Pardon me for asking but this has bugged me for a while:
I doubt if the Raphael is really produced in two hardware versions: one that supports UMTS 900/2100 MHz in Europe and another that supports UMTS 1900/850 MHz in the US?
Do any of the European friends here flash the Radio ROM v1.14.25.35 (extracted from AT&T ROM in the US) to their European version of the Raphael and with a tweak in the registry key
HKLM\Software\OEM\PhoneSetting\BandType

like
"ItemName2"="UMTS(900+2100)+GSM(900+1800)"

,
i.e., to make the UMTS 900 MHz band known to the machine, are able to connect to their 900 MHz 3G network properly?
Apparently, the 900 MHz UMTS band was not included in the default BandType after the American AT&T Radio ROM is flashed.
This is actually a very good & important question & point. Particullarly with the newer devices that are comiing out. In an effort to streamline production, HTC has changed somewhat the way the restrict devices from operating on different bands. Now you find that even CDMA & GSM device are able or would be able to operate, strictly speaking of hardware, on one or the other network except for the firmware. According to FCC documents, HTC is locking devices to networks via the firmware. This may make it possible to opperate any device on any network give that there is a place to insert the sim card.
I am using the new radio, & I have been able to use it on both the US & EU gsm frequencies. You can selct the band you want, but you need to use the band switch program as the EU band has been disabled via the registry, but it still exists within the radio firmware.

Thanks, gsleon3 for your input. I have this doubt because many people on this boards mention cross-flashing and the issues with two different hardware versions; whereas, according to Section 1.1 on "Product Features" of the Raphael Service Manual, the hardware itself supports HSPA/UMTS on 5 bands, i.e., 850, 900, 1700, 1900 and 2100 MHz and GSM/GPRS/EDGE on 4 bands, i.e., 850, 900, 1800 and 1900 MHz. Raphaels are produced in different SKUs with some bands selectively enabled, though.
I'm in Germany w/ a German O2 XDA and I've flashed the new radios with no problems. I haven't flashed to .25.35 yet, but probably will tonight.
[EDIT] Just installed .25.35, and it works 100%. We'll see about battery life tomorrow... [/EDIT]

Doing a little research I was able to unlock my T-Mobile XDA and use a Cingular SIM.
Cingular is slated to turn on their 850mhz GSM in a matter of weeks if not days. I know that my T-Mobile uses 1900 mhz, so even with the Cingular SIM in place it is "piggy backing" on the T-Mobile towers. Even after the Cingular GSM network is online I will still be using T-Mobiles towers/network because of the 1900 mhz band constraints of my phone.
My question is this: is there currently or will there be (XDA II) an XDA that can use the 850mhz GSM band?
TIA
Ray
I noticed I knew little about this, so I figured this would be the case the case for most users outside of the Americas. I Googled around a little, the results are below.
Management summary: no, the XDA II will not support the 800-850 band. There will be a few quad-band phones, and some dual 800/1900.

GSM 850
(GSM 800)
GSM 850 is simply GSM technology operating in the Cellular (800 MHz / 850 MHz) frequency band. Both the technology and frequency band have been around for a long time, but only in 2002 were they combined.
In the U.S. prior to 2002, GSM technology only operated in the PCS (1900 MHz) frequency band.
GSM 850 addresses the needs of carriers with Cellular licenses switching from other technologies to GSM.
Before the existence of GSM 850, the Cellular band was commonly referred to as the "800 MHz" band. "850 MHz" implies a different frequency band, but this is not the case. "800 MHz" and "850 MHz" refer to the exact same frequency band. 850 is technically a more accurate description of the frequency range, but 800 is the original, and more common term.

By installing GSM at 800Mhz, all we're doing is reusing the same frequencies used for AMPS/TDMA and adding GSM to them. The US has always had 800Mhz for wireless services. Nothing strange about that since there have been wireless services in that band since the beginnings of cellular. The use of GSM at 800Mhz is nothing surprising and only a natural move for carriers who are licensed to use this band. There's no law saying that GSM should be confined to 1900Mhz in the US. Europe and the rest of the world have gone Dual Band on GSM (900/1800) a long time ago. Why can't the US do the same? Besides, it is not only Cingular and AT&T, the largest TDMA/GSM US operators, who are adopting GSM 800. There are many other carriers throughout the rest of the Americas, including Canada, who use the same US frequencies and are deploying GSM 800. GSM 800 will be just as necessary and as popular as TDMA/CDMA/Analog at 800Mhz. The market for GSM 800 is just as big as the TDMA 800 market since almost all TDMA operators are moving to GSM.
Dual band GSM 800/1900 phones will be the most common GSM phones in the US soon because single band 1900Mhz GSM phones will be good for T-Mobile only which is a 1900-only carrier in the US. Just think that Cingular and AT&T amass about 40 million users as opposed to T-Mobile's 10 Million. Also, quad-band GSM phones will be more common slowly but eventually. Nothing crazy about having 4 bands since the world has had 4 wireless bands for a long time, it's only that GSM had only made it to 3 of the 4 bands and now finally made it to the 4th. For starters, look at the Motorola V600 and the NEC 515 which are the first quad-band to my knowledge.
In the future, look for more bands as the wireless industry expands into 2100Mhz and 700Mhz. Finally, the US will see other types of tri-band GSM phones, such as those that will work on 800/1900 for the US and EITHER 900 OR 1800 for other regions.

Sorry I missed read the article but overall I'm only trying to help
I don’t know how to find out what band my smartphone uses. It’s T-Mobile, so it should sell in US, where GSM band’s 1900. But my T-mobile was in box, designed especially for Russia. The letters are in Russian, a GSM band indicated on the box in big black font is 900\1800.
But device information tab in WM 2003 displays "Hardware Version: PW 10B1" (as far as I understand that means 1900 band). In spite of this on the back of my device is a sticker with PW10A2 sign. Where's the truth?
Maybe my device uses 1800 frequency?
But anyway in the band selection tab there's only 2 bands 800 and 1900 (
If my device supports 1800 band, how can I activate it?
The seller’s support tells T-mobile MDA supports 1800… But they can’t explain how to enable it.
I don't know whether connected my second problem with previous. I think it is.
Sometimes my device doesn't find network after it lost it. Example: after leaving an underground subway station. To find a network I have to turn the phone off and then to turn it on.
My radio version is T310. If this problem doesn't connected with the first, maybe I just should change a radio version to a newer one?
The sticker tells the truth normally. Are you going in to bootloader to choose your band?
How can I choose GSM band through boot loader?
Enter bootloader by holding power button while pushing stylus in reset hole, when bootloader appears push the button below antenna, you will then have all gsm options, choose 900/1800.
You may be S O L!!!
You better hope your XDA is not a 900/1800 MHz one otherwise you're going to be SOL unless you plan on living overseas because here in North America, the wireless carriers like AT&T Wireless, Cingular Wireless LLC and T Mobile USA use EDGE/GSM/GPRS on the 850 and/or 1900 MHz GSM aka Next Generation network. 900/1800 MHz GSM is used overseas and is considered the international GSM bandwidths. Cheers!

Hey,
The T9193 version of the HD2 has the radio bands 850/2100 in it for HSDPA 3G speeds, but just the 850 band is needed to support AT&T's 3G service in the US.
Would it be possible to create a new radio ROM that disables/turns-off the 2100 band for U.S. users, since this band is useless anyway, and it may help extend the battery life of our HD2 by not having to power the 2100 section of the radio, especially if it makes any transmit attempts by the phone on the 2100 band (transmitting uses a lot more power then receiving).
Any chance of this?

T-mobile is also using HSPDA/3G @ 850 also and nowhere else? I hope so because pretty much half or better of the users of these forums are T-Mobile and *not* AT&T subscribers. Jus sayin.

I don't believe the T9193's radio has the 2100 Mhz band, otherwize I'd be able to use it in my area to get 3G coverage. (We only have Edge on the 850 Mhz band here)

I'm pretty sure the T9193 has the 2100 band, but 2100 is useless in the US because AT&T uses 850/1900 for 3G. The T9193 is an Australian phone made for Telstar (their cell phone company). The 3G bands used over there are 850/2100. So, because AT&T also uses the 850 band, thats why we are able to use this phone with AT&T's 3G here over in the US.
However, the 2100 band of the phone is useless in the US because is was intended to be used for 3G in australia.
The good news is that AT&T is phasing out the 1900 band for 3G and switching everything over to 850, so the HD2 will just get more and more 3G coverage as time goes on and then even the 1900 band won't be used anymore so it would be irrelevant if the HD2 has a 1900 band or a 2100 band because both would be useless.

Well, you neglected to say where "here" is
The best available combination for world-wide 3G access is 850/2100 Mhz. This is because:
1) 850Mhz is used in Canada, US, S Americas, Aus, S Africa for 3G broadcasting in regional areas (and in some city areas)
2) 2100Mhz is used in Asia, EU, Aus cities for 3G broadcasting
This is due to the actual physics of velocity = frequency x wavelength
Some telcos use 1900Mhz in the cities, but also broadcast in 850Mhz
Other telcos use 900Mhz in the regional areas, but also broadcast in 2100Mhz in the cities
ATT in the US uses 850mhz in the regionals and 1900Mhz in the cities. This ensures that "their" PDA's cannot use other SIM's - I have no idea why the dumbed-down US market meekly accepts that
The perfect combo is tri-frequency hardware, such as PDA manufacturers used to provide but do not any more (no excuses, it's just straight cost-cutting and sleight-of-hand marketing BS to suit the greedy telcos)
The HD2 released in Aus through Telstra is hardware-filtered for 2100/850 Mhz, the best available combo for world-wide use (not perfect, of course)
The HD2 released in EU/Asia is 2100/900 Mhz. This will access 3G in most cities world-wide (note that China uses 2100/850) but has limited coverage in regional areas - yes, I know there many 900 Mhz deployments but these are very limited geographically
The HD2 released in the US is 1900/850 Mhz. This is very limited for world-wide cities and excludes 3G coverage for those countries that use 2100/900 Mhz
None of this has any relation to GSM coverage, so please do not confuse them
Is the hardware actually different?
I live in NZ and unfortunately bought a T-Mobile unit which is set up for 1700/2100mHz which means that when in the cities I get full broadband, but in the regions I only get dial up speeds through GSM.
My question is does anyone know if the hardware could actually use the 900mhz broadband - or is it a pipe dream on my part that hopefully someone will release a ROM to access some previously hidden hardware?
I do recall with my Touch that there was a GPS built into the hardware that no-one was aware of for a year or two!

... In the AT&T and International versions of the Atrix... why can we not enable HSPA/UMTS on 900MHz through flashing radios or other software means?
Edit: Phone is an unlocked AT&T version on O2 UK with O2 sim.
Because the 900MHz band that the Atrix uses is part of the quad-band GSM, which is 2G/EDGE, not UMTS. Those are two different standards.

But the international supports UMTS/WCDMA/3G/3.5/HSDPA/HSPA/HSPA+ on 900mhz going by all of the spec sheets I read.
UTMS is 3G. HSDPA is 3.5. A standard of WCDMA. HSPA is another WCDMA standard which again is a 3G Technology (3.7G?)... Either way they all come off the same 3G cell

More than likely the carriers have locked the radios and/or hardware. It's like other carrier's world phones will not work on AT&T/T-mobile, even though they technically can support those bands.

There doesn't seem to be any logic to why other than software as the radios taken out of all firmwares work on both versions. The only logical answer is software (if I could SBF flash a UK firmware, not CWM that would help, but there was other differences with the mainboard right?), or its the same chip just slightly modified without that band included.
I was mooching around system folders trying to find anything that could give me a clue, but to no avail.
I think it has something to do with what module is used, which is a hardware component. I know the AT&T Atrix uses the Qualcomm MDM6200 but I have no idea what other versions use.
I might be wrong though.

Indeed, so logic would say that if we flash international radios for a different module (if they are different) would soft brick the phone or cause the phone to no get any kind of reception what so ever.
I do find the international radios and att radios (other than the stock and 1.87) make the H+ signal level not go over 1 bar.
I'm not sure about bricking the device but I know they usually have those radios locked down pretty good which is why most people need to buy unlock codes or get their carrier to unlock their phones for them. It's not very common that end users can crack them.

SIM Lock and Radio locks are two completely different things. SIM locks are easy to break with a £10 note and a guy with some device, a radio lock is more difficult we dunno if its hardware or software.

Since Nokia does clearly say everywhere else except the US that 920 does support 1700Mhz (for obvious reasons), I wonder if the hardware in the AT&T version will be the same as in the int'l version and it'll just be a matter of unlocking the phone to use it on TMo.
Opinions?
I noticed that too!!
Its now PentaBand WCDMA/HSPA+ at 42Mbps. They added WCDMA 1700Mhz band on the specs.
Originally when the phone was announced last month was listed as QuadBand WCDMA missing the AWS band at 1700Mhz.
If this is true it means one of the following:
1.The band was always there and for some reason software locked and they decided unlock it and release it as a PendaBand.
2.They listen to the complaints (pretty much the same way they did and released the Cyan Color) as the missing AWS band was one the biggest complaints especially from T-Mobile USA subscribers and they decided to include it as well.
3.It is just a typo and Lumia 920 is still QuadBand HSPA.
4.It was a typo from the very beginning and Lumia 920 was always PentaBand.
Now assuming the the phone is PendaBand HSPA+ it will perfectly work with T-Mobile USA current 3G at AWS and with the reformed Network at 1900 they are preparing. It will work with both at 42Mbps speed.
The original unlocked Lumia 920 listed the following 5 LTE bands 800 / 1800 / 2600 / 900 / 2100.
If the unlocked phone comes with those LTE bands will be incompatible with T-Mobile USA upcoming 4G LTE network.
However the American model which AT&T will carry exclusively has the following LTE bands 700 / 850 / 1700 / 1900 / 2100
If Nokia also release an unlock/unbranded version of the American model with the above LTE bands and PentaBand HSPA+ this model along with the 42Mbps HSPA will also support T-Mobile's upcoming 4G LTE that coming mid of next year with theoretical speeds of 100Mbps.
Releasing this device will be the perfect option for T-Mobile subscribers as it will be future-proof for their upcoming LTE network.
I am curious to see whats really going on here. Meanwhile I am crossing my fingers. :good:
So Nokia needs to release a international us version?

Unlocked/Unbranded version of the American model is the correct way of putting it.
Nokia used to have to versions of the unlock devices in the past. The regular version which was usually the European/International model and the NAM versions for North America.
Many devices came like that in the past including the N95 & N95 NAM, 5800 & 5800 NAM, N97 & N97 NAM etc.
All had QuadBand GSM and different bands for 3G, the NAM versions had the American bands for AT&T USA and Rogers for Canada.
Now that PentaBand is standard for 3G/WCDMA, they need to release (and I hope this is the case) the European Model with the European LTE bands and a "NAM" model with the American LTE frequencies.
I guess time will tell what exactly the case is going to be.
But again this is for LTE. Assuming that the information on the spec-sheet is correct and the Lumia 920 comes with WCDMA/AWS 1700 then it will work perfectly with T-Mobile USA and AT&T's HSPA+ at 42Mpbs.

Unfortunatly number 3 is the correct answer.
According to WPCentral.com the AWS 1700Mhz WCDMA support for T-Mobile 3G that listed in specs are just a typo on the website.
If this is the case, you can still use the Lumia 920 under T-Mobile 3G at 1900Mhz.
T-Mobile is reforming their Network and releasing 3G to 1900Mhz now, the problem is that we do not know what markets/areas has this already or how fast the project is moving on and when it will get complete..

That's wrong, because this phone will be using the Snapdragon S4 Plus (MSM8960) which uses Software Defined Radio (SDR) for determining their bands. Obviously you cannot use all at the same time, but any one at any time. The HW supports this (according to the Qualcomm reference design), and if it hasn't been supported before in this chipset, it's probably due poor modem programming and/or unstable behavior, and/or band/bandwidth throttling by service providers networks. It's also an efficient way to make sure your Verizon mobile cannot use AT&T networks and vice verse...

That is why I said its Number 3, according to WPCentral. I am aware of the SDR in the latest generation of Snapdragons, however as its name mention its programmable, meaning they may have turn off the AWS...
For me it doesn't make any sense to list the phone originally with QuadBand WCDMA and then add AWS and list it as a PentaBand.
I mean if it is wrong and its missing the AWS that is making the original listing with QuadBand the correct one, so why they bother changing it?
In the other hand if the SDR scenario applies and the AWS is already there, they may just heard the complains and simply turned ON the AWS band, that is why they added in to the specs meanwhile the Nokia representative that WPCentral reached may not be aware of the new specs yet...
All these are different scenarios, unless we have an official clarification from Nokia, we cannot know for sure until Lumia 920 its been released.
PS. Can you post the link with the detailed specifications of the Snapdragon S4 detailing the SDR? The specs I found does not include any information regarding this. If I am not mistaken and remember correctly SDR is affecting LTE only and its able to catch from 700Mhz - 2600Mhz (for LTE), its programmable to deliver everything between these bands but limited to deliver 5 Bands at a time. I do not remember mentioning WCDMA to be compatible with the SDR, but I may be wrong on that. Please feel free to correct me if that's the case.
According to FCC documents, looks like AWS is there. Question... Will it be disabled in the AT&T version? Unlock possible?

I read that the FCC Documents for the AT&T model are mentioning AWS (1700) for LTE. This is normal as AT&T's LTE is operating also in AWS.
I didn't read anything regarding AWS for 3G/WCDMA.
If you read back, it specifically mentions wcdma 1700. Document differentiates between lte freqs and wcdma ones.
