The Motorola XT1058 is likely to be the highly anticipated X Phone, we have already seen benchmarks of the device and pictures with AT&T branding on, leading us to suspect the phone will come on all four major carriers.
Verizon and Sprint run on the CMDA 4G wireless variant and leaked documents on the X Phone revealed its brother, the XT1060. This phone will be exactly the same as the AT&T version, but with different wireless technologies.
What we cannot understand is the lack of a T-Mobile varient, it could just be running on the same technology as the AT&T version and has not been pictured, but it seems a little odd to leave one carrier out.
The X Phone is expected to be powered by a 1.7GHz dual-core Snapdragon S4 Pro chip and 2GB of RAM, the phone may come with the first taste of Key Lime Pie or Android 4.3.
