Motorola DROID RAZR MAXX, RAZR, Bionic & DROID 4 capable of running on AT&T and T-Mobile
Now if you thought that would stop these 4 devices from working on AT&T or T-Mobile then guess again. Developers have successfully modified the radio to allow these DROID-branded devices to run on GSM networks like AT&T and T-Mobile. The developers have posted pictures of he devices utilizing the AT&T 3G network but haven’t been able to get it to work on T-Mobile HSPA just yet.
According to the developers, they are working hard on getting it working on T-Mobile’s HSPA (currently only working on EDGE) and also create a public release so users are free to move to purchase the top Motorola devices for use on AT&T and T-Mobile.
The Motorola DROID RAZR MAXX in particular stands out from the pack as it is the newest and also features unbeatable battery life. We’re certain many AT&T and T-Mobile users would love to get their hands on one.
