Moto maker website says that it is Unlocked GSM, so it for sure will not be locked to Net10. It is likely (but not confirmed, hence my question near the top of the thread) that it will be the XT1053 model (up until now known as the Unlocked/T-Mobile/Developer Edition model). This late in the game I can't see Moto spinning a new firmware for a new model of the X, but you never know. I certainly would hate to get it and find out that I have a Moto X crapped up with Net10 branded firmware.
I'm probably just going to go ahead and order one, if it isn't an XT1053, I'll send it back for a refund.
