Gather around folks, there’s more jelly beans to be had. The Motorola Photon 4G has received an unofficial CyanogenMod 10 (CM10) ROM which brings the latest version of Android aka Jelly Bean to the device with features such as a smooth as butter interface, voice recognition like Apple’s Siri, smarter keyboard etc, along with the proven performance of CyanogenMod as well as its customization options, thanks to XDA Recognized Developer jokersax11.

NOTE: The ROM is a work in progress and still in the early stages of development, so expect bugs and issues to be present as well as things that don’t work properly. Also, since CM10 is still under development, not many CyanogenMod customization features are currently present in the ROM.

Let’s see how CM10 can be installed on the Motorola Photon 4G.

    does 4G still works? :-/ I heard some ROM upgrades do not support sprint’s 4G, so you end up stuck with 3G only mode :-p

      arie meirman…unlocking the bootloader on the phonton WILL break 4G! If you want 4G, do not do this.
