VP of Product Management at Motorola, Punit Soni, helped shed some light on some "stuff" that wasn't mentioned in all the Moto X hoopla. According to Punit; Sprint, US Cellular, Rogers and T-Mobile networks will have an unlockable bootloader with Big Red offering a developer edition. Motorola will also be offering a general North American Developer Edition. We are going to venture to guess that since the AT&T model wasn't named specifically as having an unlockable bootloader, the North American Developer Edition will be an unlocked GSM model with AT&T bands. Why this wasn't mentioned or why these details were so murky to begin with is anyone's guess, but there you have it folks.
