Motorola Photon Q LTE was released in July, the device is preloaded with Ice Cream Sandwich (Android 4.0).

For those of you who really want a taste of Android 4.1 running on Photon Q, you can install the phone with custom ROMs.
Installing a custom ROM (CM 10, MIUI 4, AOKP JB, etc.) is fairly easy on this phone, since the device has been supported by a Motorola Unlock program that allows you to unlock the phone’s bootlader.
