can anyone provide me the simple steps to upgrade to 2.2 from 2.1 android OS for X8 Xperia mobile. If so, is that fine to do myself without the help of sony erricson departmental store ?
There's no official upgrade to 2.2 for X8 Xperia, Wikipedia says. You can install a third-party ROM, though -- it seems the latest Cyanogenmod 7.1 is available for this device. Which is even better, considering that ROM is based on Gingerbread 2.3 instead of Froyo.
