From what I understand, T-Mobile can and will unlock this device for me if I ask them (nicely) meaning I could then use it with AT&T. Is my understanding correct?
My other options are to buy one from T-Mobile or get one from Motorola's website. Same question with these phones: Even if they are locked to T-Mobile at first, can I get them unlocked and use them on AT&T?
Thanks for any and all help!
I don't know that there is a "T-Mobile Branded" X, and I don't think T-Mobile sells the X directly (at least it isn't on their web site).
Your choice, is the GSM UNlocked (includes T-Mobile sim) from Moto Maker web site, or the GSM Developer Edition... why?
These are the only way to get a Moto X that supports HSPA/HSPA+ over AWS (1700mhz) that T-mobile uses. History or why is this a consideration: When T-mobile started rolling out their HSPA/HSPA+ network, they did so on AWS(1700mhz) and are the only carrier to do so. While they are re-farming their 1900mhz from EDGE to HSPA+ in many areas, that isn't complete, so if the phone doesn't support HSPA/HSPA+ on AWS, it will fall back to EDGE in those legacy areas which remain.
Now, what is the difference between the GSM Unlocked and GSM Dev Edition? Kind of simple...
The GSM Developer Edition comes only as 32gig with black face, woven white back, silver accents (buttons and camera ring), and says Developer Edition on the back.
The GSM Unlocked (includes T-Mobile SIM) on Moto Maker can be ordered as 16, 32, or 64gig, and the face, back and accents can be customized, along with other customization.
BOTH are SIM unlocked out of the box. Both can be bootloader unlocked, however doing so voids the warranty on the GSM Unlocked version but not the Dev Edition.
Both of these editions support the same GSM/EDGE/GPRS/HSPA/HSPA+/LTE bands and frequencies. In fact, they are the same "board' inside, use the same roms, etc. i.e. other than the look of the outside & customization options, and bootloader unlocking voiding vs not voiding the warranty, they are the same phone. (hence the GSM Dev Edition being the preferred choice so you can unlock the bootloader and easily root it without voiding the warranty).
If you are on T-Mobile today, you could buy the ATT version at no contract direct from Moto, BUT... you can't unlock the bootloader (moto doesn't give out the codes for ATT, Verizon, Republic wireless and a few others), ATT Wont sim unlock it (so you could use with T-Mobile) unless you are their customer for a certain period of time, and it doesn't support HSPA/HSPA+ on AWS. While the ATT X does support 2 extra LTE bands, those bands are not currently used in the USA.
Hope that makes sense.
