Verizon has had an on again/off again love affair with “global” phones – phones that carry CDMA support for the U.S. and a GSM radio for frequencies abroad. More often than not, however, the GSM radio is only supportive of GSM frequencies not used in the U.S. making any hackery to unlock and run on a local GSM carrier out of the question. But as it turns out, the newer generation of silicon inside of specific VZW phones is truly global, supporting foreign and local GSM networks as the crafty folks at XDA have found.
An ongoing thread over at XDA has Android dev/hacker P3Droid (@P3Droid posting the details to the relatively low-key, easy-to-do hack that allows Verizon’s Motorola DROID 4, Bionic and RAZR to function on AT&T’s HSPA and T-Mobile’s EDGE networks thanks to the globally friendly MDM6600 chipset.
The instructions really aren’t all that involved (found on page 2 of the thread) and entail a simple flash of a custom ROM along with a (very) small amount of editing a file or two and finally, adding in your carrier’s APN settings to get data working.
Quite honestly, this discovery is awesome. But don’t take our word for it. Head over to the XDA thread linked above (or below) and check out the ongoing discussion.
