Make Your Photon Work on US GSM Carriers
One of Sprint’s major selling points with the Motorola Photon 4G is that it is a world phone. In addition to picking up service from Sprint’s CDMA network, it can also connect to GSM networks worldwide, allowing travelers to continue using the phone despite not being in a Sprint area anymore. However, users have found it quite hard to get working on domestic GSM networks such as AT&T and T-Mobile, and it actually hadn’t been done yet. Until now, that is.
XDA Senior Member halfevildruid released a modem that unlocks the Photon and allows it to work freely on AT&T and other GSM networks. The method does have its issues though. Using this radio and switching to a domestic GSM network will break your ability to use CDMA completely. So once set up, users would no longer have access to Sprint at all, and would have to rely on whatever GSM network they wished to switch their Photon to.
The method itself is relatively simple. Be sure you’re on the firmware that’s been tested, flash the radio, pop in your GSM SIM card, and go through a set up process. Not too terribly difficult, but do be sure you’re on the suggested firmware versions because otherwise, things may go drastically wrong.
While the radio currently breaks CDMA, there is a light at the end of the tunnel. Users can restore their old settings and get back to Sprint with a couple of flashable zips provided by halfevildruid. Not enough? An upcoming update will no longer break CDMA, allowing you to use Sprint and GSM networks at the same time. So those who don’t want their CDMA broken only have to what a little longer.
