Prematurely outed earlier today, Motorola RAZR Developer Edition has been officially announced just now and can be pre-ordered by European developers. It has been priced at 499 Euros and comes with no warranty. Clearly not for everyone!
Specifications of MOTDEVXT910 are exact same as the retail RAZR apart from the unlockable bootloader. Motorola shop has not mentioned any ship date, so you will have to wait for a while to get your hands on the device.
