Over two months after it first debuted for ATT customers, the Moto Maker — Motorolas online customization tool for the Moto X— is no longer exclusive: today, its expanding to Sprint, T-Mobile, and Verizon Wireless. Furthermore, Motorola promised today that Android 4.4 KitKat would be rolling out for the Moto X soon. In the mean time, the Moto Makers expansion to the big four major US carriers is a welcome addition, allowing new Moto X buyers to choose from a set of colors for the devices backing, front edge, and accents. If youre paralyzed by choice, a Motorola Facebook app can link to your photos to act as a color picker.
