The rumored X Phone being developed by Google and Motorola unit is headed to AT&T later this year. A recent filing with the Federal Communication Commission revealed that the device, which carried the codename Motorola XT1058, will support AT&T’s LTE and HSPA+ networks. The smartphone didn’t include CDMA radios for Verizon and Sprint’s networks, however a new leak suggests a CDMA model is also in the works. A configuration file reportedly from a leaked Motorola USB driver that was obtained by Droid-Life revealed a device with the codename XT1060, similar to the recently leaked AT&T model. The file also confirmed that the smartphone will be equipped with a dual-core Snapdragon 4 Pro processor and support for CDMA networks, although it isn’t clear if it will be compatible with Verizon, Sprint or perhaps both carriers.
