This smartphone will not receive any updates beyond Gingerbread but now you can enjoy Jelly Bean Android 4.1.2 on your device thanks to Pacman ROM a firmware that incorporates the best of Paranoid Android, AOKP and CM10.

However, the Android developer community has created an excellent ROM called Pacman, Jelly based on Bean 4.1.2 and combines the best of Paranoid Android, AOKP and CM10, three of the most popular cooked ROMs.

Pacman ROM is a very stable custom ROM based on Android 4.1.2 Jelly Bean incorporating features very interestings such as the ability to modify the interface to use the device as a smartphone or tablet and various settings, functions and options that are not available in the stock Android ROMs.
