The Motorola Milestone 3 XT860, also known as Motorola XT860 4G (Canadian version), was announced in August last year and released in September. The XT860 was touted to be the thinnest QWERTY smartphone at the time of its release. Except for the difference in network support, both the regular and Canadian versions have many features in common. The regular version runs on Verizon Wireless network with 3G support, while the 4G version is supported on Bell Mobility's network carrier. The phone ships with a predominantly striking QWERTY-slider keypad and portrays identical looks of its predecessor - Motorola Milestone.
