A revision of the ZTE Grand X (read our review) has just passed through the FCC, undoubtedly destined to land on T-Mobile. Not only does the device have FCC clearance to operate on T-Mobile's 1700/2100MHz AWS frequencies for HSPA+, but also has a nice bit of T-Mobile branding on the back. Other than the new radio and branding, we're likely looking at the same device that was released internationally a few months back -- a 4.3-inch qHD (540x960) screen, Tegra 2 processor, 5MP camera and stock Ice Cream Sandwich.
T-Mobile regularly picks up some of these less than mainstream devices, and usually ends up offering them at pretty compelling price points. The Grand X is no slouch by any means, and should be a solid mid-range offering for many customers.
