There are different versions of the Droid 3: XT862 (USA), XT860 (Canada), XT860 (Brazil), XT883 (China).
I'm wondering whether there are any differences in the hardware between these version, especially now that the Droid 3 has been rooted.
When looking the official Motorola specs, I find:
1) XT862 has HSDPA 10.2 Mbps in the consumer specs, but HSDPA 14.4 Mbps in the developer specs. Both are HSDPA category 9/10. According to http://en.wikipedia.org/wiki/High-Speed_Downlink_Packet_Access, category 9 has a approximated max rate of 10.1 Mbps and category 10 has 14.0. So maybe Motorola took the value of category 9 instead of 10 when typing the consumer specs, while they should have listed the higher rate of category 10?
2) The Brazilian XT860 has HSUPA 7.6Mbps, while the Canadian XT860 and the XT862 have HSUPA 5.76 Mbps. But because the Brazilian and Canadian are both are XT860, I would expect this rate to be the same, instead of being different.
3) The XT860 doesn't have CDMA 800/1900 and CDMA EV-DO Release A, while the XT862 and XT883 do.
4) The XT862 and XT883 appear to be the same, although I haven't looked in the consumer specs of the XT883 (because it's in Chinese).
Rationaly, when a characteristic of device isn't listed in a specification, you cannot conclude that the device doesn't have that characteristic. The specification might simply be incomplete, but still be correct. But when a characteristic isn't listed for which you would expect it to be listed when would have that characteristic, then the specification suggest (but not conclude) that the device doesn't have that characteristic.
So rationaly, the XT860 might (or might not) have CDMA support, and the Canadian XT860 and the US XT862 might have the same higher HSUPA speed as the Brazilian XT860. And, according to the specs, the XT862 does support 14.4 Mbps HSDPA, although with doubt because the consumer specs list a lower value.
So based on the official specs it is difficult to derive the real maximum speed specs and all features
The best thing would be if someone physically opened all Droid 3 versions, and list the hardware chips. Like this:
http://www.ifixit.com/Teardown/Motorola-Droid-3-Teardown/6108/1
Which says the XT862 has the following hardware chips:
-Qualcomm MDM6600 supporting HSPA+ speeds of up to 14.4 Mbps
-SanDisk SDIN4C2 16GB MLC NAND flash
-Elpida B4064B2PB-8D-F 512MB RAM and TI OMAP 4430 CPU
-Triquint TQM7M5013 Linear Power Amplifier
-Avago A2F1106
-A5005 K1116, A5002 K1118, A5001 K1118
-Kionix KXTF9 11425 1411 three-axis accelerometer
-The Qualcomm PM8028 chip works in conjunction with the Qualcomm MDM6600 to provide wireless data connection to the phone.
-Hynix H8BCS0QG0MMR memory MCP containing Hynix DRAM and STM flash
-ST Ericsson CPCAP 006556001
-WL1285C 13M1HH3
-6792A 1113 T3971

I expect that the XT883 has the same hardware. But the more interesting question is whether the XT860 also has this hardware.
From this list, when it comes to mobile networks, the most important part is probably the Qualcomm MDM6600 and maybe also the Qualcomm PM8028.
The specs of the MDM6600 can be found in http://www.docin.com/p-162606115.html . If I understand it correctly, it supports both CDMA and GSM networks.
But even if a mobile device has a MDM6600 in it, which by itself supports CDMA, it doesn't mean that the mobile device supports CDMA. This is the case for the IPhone 4, which comes in a GSM/AT&T version and a CDMA/Verizon version:
http://www.ifixit.com/Teardown/iPhone-4-Verizon-Teardown/4693/1
http://www.ifixit.com/Teardown/iPhone-4-Teardown/3130/1
Interesting is the following quote for the CDMA/Verizon IPhone 4:
The Qualcomm MDM6600 chip supports HSPA+ data rates of up to 14.4 Mbps and CDMA2000® 1xEV-DO Rev. A/Rev. B.
This is the same chipset as the Droid Pro world phone. It supports both GSM and CDMA—which means that Apple could have supported GSM!
Why didn't they? It may be that it was easier to design antennas for a CDMA-only phone -- this phone supports two cellular frequency bands, while Apple supports five bands in the GSM version.

So even when a phone has a chip that support CDMA, other parts of the phone might not (because of design reasons), causing the phone not to support CDMA.
But why would Motorola first release XT862 that supports both GSM and CDMA, and later release the XT860 with CDMA stripped off? I would expect that they would do this only if stripping CDMA from the XT860 would benefit some other feature. Any ideas?

Speaking with a bit of experience with manufacturing, there isn't a lot of sense in making too many models, because the price savings based upon leaving out an antenna on one model would easily disappear in the context of devoting another production line to another model.
So, I have the strong impression that they are all cdma/gsm capable, though differences in firmware probably define the active radios.
This is a guess, though, so take it with a grain of salt.

For us Europeans this is an interesting question, because if the XT860 and XT862 have the same hardware, there is no reason to get the XT860 other than it doesn't have the verizon logo (now that we have root).
The XT862 can already be ordered in unlocked state while the XT860 cannot.
I also would think that creating just 1 phone is way more convenient and way cheaper for motorola, so I'm curious as to whether all "droid 3's" are the identical.
CDMA only works in america, and a couple other small countries, and only on a couple carriers, so support for it ONLY makes sense in the XT862. the rest of that world went GSM and it's various 3g offshoots. the differences between the 860 & 883 are to support what those countries run on.

But, like Sadrak86 said, from a manufacturing cost point of view, it doesn't make sense to simply remove CDMA support because it isn't used in another country. Why would Motorola release a global phone (Droid3/XT862) and then a month later release the same phone but this time non-global phone (XT860) by removing CDMA support. There must be a better reason.
I can understand them making specific versions of specific regions, but not with different hardware components if they could just disable them software-wise.

I also think that if they can control it software wise without extra costs compared to hardware wise, they will choose software wise. But if the XT860 has CDMA removed software wise, than why didn't they remove GSM from the XT862.
This brings back the question: why would they first release a global phone (XT862), and later release the same phone (XT860) with less features and a higher price.
A reason could be that by removed hardware features (CDMA) from the XT860, other features (GSM) might perform better.
Found this page called Motorola XT860 4G Fact Sheet, but is more press release page. But it confirms that the XT860 has a QualComm MDM6600 (which supports both GSM and CDMA). The XT860 contains a GSM compatible antenna, but the question than is: does the XT860 also contain a CDMA compatible antenna?
This question is very interesting for all non-Americans. Because the following choice depends on it:
-Should you buy the cheaper, more widely available, and more network supporting global XT862? or
-Should you buy the more expensive, less widely available, less network support, but (possibly) better GSM signaled XT860?
At the moment we don't even know whether this option/choice exist. If this option doesn't exist, then there is NO reason at all to buy the XT860.
This (whether the XT860 has a CDMA antenna) is something that can only be proven by a teardown (physically open a XT860). I hope some guys will create an iFixit page for it.

Well unless you don't like the verizon logo
But ye you're right ^^^
There are plenty of reasons if you are GSM user. Verizon altered/disabled some GSM features of the phone like call forwarding settings for example. Droid 3 is certified/supported only with the Verizon SIM in it. There are already reported cases phone doesn't play nice on certain GSM networks across the world. Not to mention unlocking issues which were a wide spread issue with Droid 2 Global and there seem to be already one such case with D3 on this very same board. You can't use D3 on AT&T in the States either.
All those problems are easily overcome by going XT860 (pure GSM phone). Since I had to experience most of these above mentioned issues myself with my own Droid 2 Global in the past year, I went XT860 over D3. And I do not regret my choice. I do not use the phone on Bell (I unlocked and use with another operator in Canada), but I have no issues. I can go to the States and use the phone there just fine too.
So there are enough reasons to justify few bucks more when buying the phone.

Can this be fixed by rooting the phone? If not, then the hardware must be different.

This might equally be the case for the XT860? Probably too early to tell?
(Both the XT862 and the XT860 have Qualcomm MSM6600, according to the Motorola fact sheet. But it could also be the antenna that determines the quality of the signal, instead of the chip.)
that issue on the motorla forums is due to the phone not being able to read the mcc and mnc codes from the sim card. buying a new sim fixes it (at least in my personal experience)

No - because this is a baseband feature (radio firmware). You can't alter the radio image unless bootloader is unlocked as it is signed. Root will not help.

I doubt - unlocking procedure is dead simple. And code is just 8 digits long. Good thing is you can't hard-lock the phone - after 1/2 hour being left on, or so, it will let you enter codes again.

This is something the operator does. And the only one operator in the world I've ever seen doing this is Verizon. I doubt that would be a case with non-Verizon phones.
Above case is another example of issues with D3 and sim cards - D2G suffered same issues too. Using Verizon world phone with non-Verizon SIM card in it is a hit or miss, at best.
So how could we find out whether the baseband firmware is different on the XT860 than on the XT862?
The baseband firmware is absolutely different. One is a CDMA/GSM global device and the other is GSM only. Despite sharing the MDM6600 chipset, they are very different.

Would it be possible to flash the XT860 firmware to the XT862 droid 3?

Wikipedia says:
Code division multiple access (CDMA) is a channel access method used by various radio communication technologies. It should not be confused with the mobile phone standards called cdmaOne, CDMA2000 (the 3G evolution of cdmaOne) and WCDMA (the 3G standard used by GSM carriers), which are often referred to as simply CDMA, and use CDMA as an underlying channel access method.

So I've been doing some research on unlocking the bionic to work on other networks. I've found several websites that clam the bionic can be unlocked, you supply them with your bionics numbers, and they email the unlock codes. This isn't just for the bionic, they support multiple phones. Just curious as to if anyone has tried this with the bionic, or any other phone before I put money into something that doesn't work.
Sent from my DROID BIONIC using XDA App
Don't put your money into it. I used a service and it took them 5 days to get me my code and instructions. I installed the unsupported SIM card like the instructions said, booted the phone and received a message that said the SIM card was from an unknown source, but didn't provide a dialogue box to type in my code like the instructions said it would.
I have been researching how to input that code since, but no luck. I read there was a way to input it using Radiocomm, but I can't get version 11.11.11 to install correctly on my computer and don't know what to select for the Bionic.
Here is Motorola's official spec sheet page for the Droid Bionic: http://developer.motorola.com/products/droid-bionic-xt875
Look very carefully at one particular section
Connectivity
WAN: VOICE BANDS CDMA 800/1900, LTE 13
WAN: DATA BEARERS EVDO Rev. A , LTE
What does this mean for you? It means it's essentially impossible to use the Bionic on anything other than Verizon. The radio on the Bionic has ZERO support any GSM protocol or bands.
If you're lucky, and someone comes up with a method, you might be lucky to use it on a cheapo CDMA regional carrier like Cricket Wireless. Have fun crawling on 3G only.
Well, it sure would be nice to be able to use it on an LTE network overseas with a prepaid SIM card.
Wasn't one of the original selling points of LTE is eventually all phones and carriers supporting the same hardware spec? That's not to say that any given phone will work with any carrier, but at least that's the carrier's choise, not dictacted by completely incompatible technologies, GSM vs CDMA.
It's just sad that as the tech to make everything interoperate is poised to take over the carriers and the governments that regulated them (at least in the US) have no interest letting them them do so.
Funny thing is a large block of LTE spectrum was sold with the caveat that the carriers that won the auction cannot restrict the hardware and software that uses that spectrum. Apparently Verizon is not complying with that law.
http://pocketnow.com/smartphone-news/editorial-are-verizon-lte-data-caps-and-handset-locking-illegal
Even if it were unlocked, you wouldn't be able to use it on an overseas LTE network.
So I was searching around XDA and found that they finally have found a way to unlock the AT&T and T-mobile bands on the Droid 2 Global. http://forum.xda-developers.com/showthread.php?t=1057064&page=3 I was wondering if we could benefit from this thread in trying to get the Droid 3's U.S. bands unlocked. The reason I ask this is because those of us on AT&T don't have a great selection of dual core android devices and this would be a great feat. I hope with the power of the XDA developers we can get this badboy's bands unlocked
I believe TBH is/will be working on this for the D3. Patience is a virtue...
I have been looking into this but I am not confident it will ever work.
The band lock has been moved into the radio image itself and without the ability to sign a radio image ourselves we won't be able to alter that. It is no longer accessible in the NVM as it was on the original firmware builds for D2G and Pro. This was done at the request of VZW to make it more difficult, if not impossible to do.
This is just a thought and I doubt it even make sense but could the radio be stripped from the Droid 3's gsm cousin the XT860 4G. They are virtually the same phone besides the fact one is CDMA while the other is GSM.

I'd suggest you buy a XT860 from Bell, in Canada. They use the same 3G bands as the AT&T network. It would also make it easier for you to unlock. Cost me 20$ to unlock mine, got the code within 15 minutes.

I don't think Verizon will necessarily be selling that phone, it will just be available to other carriers around the globe who use the GSM bands. Similar to the the different versions of the droid 3. The Verizon D3 had a GSM radio, but there were other model #s of the D3 that we release internationally in this same manner

Quick question, had the XT862, which was having some issues with the camera, so I unrooted and using my warranty. They (vzw) sent me the new phone next day (wow) but when I looked on the backside behind where the battery sits, it says it's a XT861. I googled this XT861, and I can't seem to find any information on it really, except that the parts are the same for all XT860, 1, 2 models. Same as the XT862 I assume?
I have 5 business days to return my old phone... but should be the same (XT861 should be rootable, right?)

To my knowledge there are three versions of the phone;
XT862; Verizon Motorola Droid 3 (global phone CDMA/GSM)
XT883; Chinese Milestone 3 (Same hardware as D3, different partitions, can be flashed fully with D3 SBF/FXZ as I recall)
XT860; Motorola XT860 4G (GSM only version)
It's either a misprint, knockoff, or hidden revision that was never really publicized. Can you confirm if it has both CDMA/GSM radios?
Yep. has both radios.

Those APNs are there because of the Vodafone SIM inside the phone. Also; only one data source will be connected at once, either Wifi or 3G, except for if you send an MMS while on wifi, it'll connect to 3G to send it.

It's an actual model; Chinese version. It's listed in Motorola's update schedule to remain on Gingerbread.

Here's the update schedule;
MILESTONE 3 XT883 (China)
Will remain on Gingerbread (Android 2.3).
XT861 (China)
Will remain on Gingerbread (Android 2.3)
These are both listed in the Asia-Pacific region of that chart. Though I cannot find much specific to the XT861 besides it being labeled as a Motorola Milestone 3, whereas the XT883 is just 'Motorola XT883'
Appears to be identical to the XT862, just sold in the Chinese market without the Verizon logo.
Motorola probably had to flash these with XT862 software for Verizon warranty replacements. Guess the XT862 stock ran out.
Nothing to worry about.
But the chinese version has blue keyboard highlights and other keys. http://www.mobilegazette.com/handsets/motorola/motorola-xt883/motorola-xt833-2.jpg
is the bootloader unlocked? probably not
are the US bands unlocked ???
If they're running out of stock, maybe this might be a good time for anyone considering any warranty fixes to take a chance on sending it in and possibly getting a free upgrade. What do you think, any possibility there? I'm not with VZW, but Moto says my D3 is still on their warranty, and I've been thinking of sending it in to get my hardware keyboard fixed. I've got one of the ones that frequently misses and/or sticks.
Edited to add: XT861 seems to be a pretty obscure model. I can't find anything on Google for specs, only mentions of accessories and spare parts, all of which seem to be interchangeable with the XT860 and XT862, not that that helps much.

But I would love to see them make a QWERTY Razr M, allowing a 4.3" screen without making the phone any bigger.
The photon q is nice

if you bought the extended warranty, it may be longer than the 1 year warranty. i didn't know (forgot) that we were paying an extra $5.99/mth or something for extended warranty, so we had 1+ years of warranty service per the verizon tech support. the safe mode and other stuff they make you do is ridiculous though...

Edited to add: XT861 seems to be a pretty obscure model. I can't find anything on Google for specs, only mentions of accessories and spare parts, all of which seem to be interchangeable with the XT860 and XT862, not that that helps much.

agreed. did my research as well, and damned quiet on this.. i was really really hoping the XT861 would be a secret dev edition lol..

I posted pictures, and mine are standard puke orange colored... i DID notice, that at the top of the screen, right above to the right of the word MOTOROLA, a red light turns on every now and then. very faint red light. i don't remember how I got it to turn on.. never saw that on the XT862... i previously had...
EDIT: While the baseband may support LTE, an additional RF chip is required. Sorry
As some of you may know, I have been trying to details the hardware inside the Nexus 4, and I may have made and incorrect assumption based on the fact we were told it doesn't support LTE. I believe the Nexus 4 may have and LTE capable basband chip.
The Nexus 4 uses a snapdragon S4 PRO APQ8064. This SOC doesn't have a baseband chip at all, you have to add a separate chip.
It is unknown what baseband chip is in the Nexus 4, but we can narrow it down. As can be seen on the android central home page very very clearly, the baseband version is as follows:
M9615a-CEFWMAZM-2.01700.27
The first part of that caught my eye. M9615a. For 10 points, anyone know what baseband chip is in the Optimus G? MDM9615
M9615a... MDM9615... See where I am going with this here? Seems a little coincidental. Might be nothing but I thought I would throw it out there.
If Google is getting LG to use the same parts in the Nexus 4, then it seems to me that the Nexus 4 does support LTE (although NOT CDMA, so still no Verizon or Sprint).

It may have the onboard chip, but doesn't it need a separate (a specific type of) antenna for LTE?
Wouldn't they have to test the chip's functionality at the FCC which would alert the tech writers who watch that stuff?
Those documents can be found here. You might be able to make heads or tails of any of it (I can't)
The reality is that LTE chips are significantly expensive to add to a smartphone, like in the $200 range. Part of The reason this phone can be offered for so low off contact is because it is HSPA only. I am also quite confident that they have to dissociate all of the radios inside the phone.

Is that expense attributed to the hardware? Seems a bit high to me, I would guess it is some sort of licensing fee to use that spectrum. if thats the case having it technically not supporting it would negate the fees while still possibly having the necessary radio for it. Completely speculating though.
Hi
I expect all the gobi modem range are software compatible and the base band shown is just the software identifier.

Are you saying $200 just for LTE? Umm no. Research firms suspect it added $10 to the cost of the qualcomm chip for the iphone.
The baseband chip might support LTE (most likely it does), but the phone is probably missing the required amplifiers (LNA and PA) and filters to make it work in the LTE bands.

That sounds much more likely the case. I will say that if it's possible I guarantee the amazing development community on here will have it functioning very soon after they get hands on it!
Having read some more, the iPhone 5 uses the same chip, but has an additional chip paired with it. I couldn't find out if it was to do with the CDMA models though.

Also I would guess that qualcomm has locked out the functionality even if it is the same silicon. Common practice in the industry when you are selling a lower-end variant at a lower price. That could what the 'a' added onto the part number is for.
The second chip is the Qualcomm RTR8600 multi-band/mode RF transceiver for LTE bands, and s also found in the GSIII.
Sorry guys, my bad
