It might have or might not have been asked or discussed before so I apologize if I'm asking about something that someone has already asked about. Regarding the Moto Maker customization, is it only available to AT&T customers? Or can one customize the device and pay outright for it? I'd like to purchase one for use on Metro PCS which supports AT&T's 3G/4G network in my area. I've read into many articles regarding the Moto X release on AT&T but I haven't really read anything pointing to whether availability is limited to AT&T customers. Any help would be highly appreciated. Thanks in advance.
