We have some good news, the Moto X will have an unlockable bootloader except for AT&T and Verizon variants. This was made clear by Punit Soni , Motorola’s VP Product Management.
Moto X on the Sprint, US Cellular, Rogers and T-Mobile networks will have an unlockable bootloader, and in addition, we will be offering a Verizon Wireless Developer Edition and a general North American Developer Edition.
There will also be a developer version of the Moto X for Verizon and a general North American Developer Edition (which we assume will have AT&T LTE support). No word on the release of the developer versions though.
