Hi guys, I have a bit of a dilemma. I bought my Milestone secondhand from a guy who had it imported before they were officially sold here in Thailand. I can't get a hold of him but I *assume* it's a Canadian model, as it has a QWERTY keyboard. I'd like to make sure I have the correct baseband on the phone, so that I may be able to get 3G by using a different carrier with a compatible frequency (3G is a big mess here, legal battles between the government and carriers, so each major carrier essentially has its own frequency).
So, how can I be sure which 3G system my phone was designed for?

Search in page baseband or Thailand.
But this is basically if you dont have signal, 3g I think it work through apn.
Same things with 3g licences over here so that is nothing unusual about this.

Install ROM, pick a baseband, configure APN. If you can't get a stable connection, then you have the wrong baseband. Try a different frequency set (europe, canada). If 3G never works, then your phone freq are not compatible with your current carrier.
Switch sim/carrier and try again

@etimago, you can check your baseband type in settings/about phone. What does it say there? Then we can see which one you've got.
I've got at a T-Mobile Galaxy Tab which I realy like. The one thing I wish it had was voice calling support. Rather than hack it to make voice calls, I'd like to find a model that does natively. I tried searching for which models support voice, but I just keep finding how to enable voice on my T-Mobile or AT&T tab.
Can anyone tell me which models/carriers support voice calling out of the box? If there aren't any US variants, then which International variants would work on either T-Mobile or AT&T (preferrably 3G)? I'm hoping to find a used one on eBay or somewhere and sell mine.
Only European versions have GSM capabilities. You have to buy a P1000 from a European retailer, mine is from Orange carrier, but there are plenty retailers that sell GSM enabled ones here in Europe.
Wtf are you talking about. All AT&T and Tmobile tabs are GSM too. They are exactly the same as the European Tabs with the exception of the rom running on the tab (and the Tmobile one has a different radio for Tmobiles odd frequencies).
If you want voice on your tab, just flash a stock rom that hasn't been modified by any carrier. Be warned though, the carrier will usually block voice on tablets, so it is probably a fruitless venture.
I now have the GT-P1000, which I bought over eBay from a UK eBayer. However, and in hindsight, a T-Mobile stock flashed with Over Come 2.2 and GingerBread 2.3.3 would do exactly the same but with less hassle and cheaper.
Thanks for all the help guys!

I realize that my version is GMS, but there's no call functionality. I guess I assumed that with a European version, they wouldn't block calls on it as it's not the model they sell/block. Am I wrong in my assumption? Do T-Mobile
and AT&T block calls on all models of tablets (specifically all Galaxy Tab 7s)?

Why? I guess I'm just worried about bricking my Tab and would rather use one that I can just keep updated with the Samsung releases.
If you look around, there are quite a few well written documents that explain exactly how to flash a ROM. Alterbridge and Pittbull have written one and posted it for both their Froyo and Gingerbread ROMs. If you just MUST have stock, there are also very good guides written up from Rotohammer and his stock ROMs.
There is no need to buy a whole new tab just to enable voice. Buying a European tab WILL NOT enable 3g and calls at the same time. It currently is not possible to have 3g capabilities and voice capabilities at the same time. Rotohammer has written up a script that allows you to switch between 2g+voice and 3g(without voice.) Currently, those are the options for Americans on the T-mobile network. I do not know if AT&T is still allowing 3g and voice, I had heard it's been blocked. Again, I can't say for sure.

I have a question about what the real differences between the gsm and cdma töms and tablets...
i have a galaxy tab bought in sweden and running both telia sonera and telenor mobile broadband..
and ny question is the following, i have installed both cdma and gsm custom roms and i havent seen even the sligthest difference of my tabs behaviour either with cdma or gsm so what is the big issue for all the folks in the developement section about "please do a gsm version" or "do u know when the cdma version hits the floor"
i am just a noob so please help me understand
Most times flashing a GSM or CDMA rom on the wrong device screws things up to the point where you have a real brick.
Can't comment on why yours seems ok...

Then why you said that your gsm tab with a cdma rom is working fine ?
Seriously, cdma is for sprint and verizon carriers, they don't use sim cards, gsm versions do. Us, europeans use gsm. If you flash a cdma rom on a gsm device I doubt you'll be able to make calls(I seriously doubt it will boot), because they have different drivers... etc.Try flash the sprint rom on your device for exemple and let us know if it behaves normally
Hope that clears things up a little bit.

ahh i mixed them up, i ment as u said here above of course..
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

Click to collapse
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.
Click to expand...
Click to collapse
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.

(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.

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.

While this is likely the case, it appears that all HTC M7s are the same hardware with slightly different firmwares; which appear to make the hardware slightly different, after all, every M7 can be a world phone, they all technically have access to the same frequencies(even the htc spec page shows this), they all have GLONASS and GPS, so overall I think the mainboards are identical to every other M7 with slightly different bootloadersds.
I wondered if there were some sort of 'fuses' that they flip to stick a phone to a company or region(none for world unlocked, 1 sprint, 2 att, etc); but that's just speculation, and it's loosely based on something Motorola has done so HTC may not have.

I believe it's something to do with the use of a tuneable radio that can be adapted to pick up a number of different GSM/CDMA bands though. LTE is a different story altogether though.

There's no difference between the onboard radios, but the LTE hardware is different from device to device. And there's a variant of the One produced for the Asian market with an SD card slot due to the use of smaller radios in those regions. The One is much more unified, but it's still customized from carrier to carrier, just not as much (essentially, by as much as is required).
Go flash a GSM ROM/radio and see if your phone turns into a GSM device if you're that confident.
