bringing AOKP to Xperia
AOKP is an awesome custom Android firmware. (just like MIUI and CyanogenMod).
AOKP is based on AOSP and looks as vanilla as possible, and focusses on lots and lots of user-friendly features. What makes it different from CM is that there are many more user-customizable features.
