I suggest that you try reinstall/repair the phone software using PC Companion: 

http://www.sonymobile.com/update

In PC Companion, press start on Support Zone > Start on Update the phones software > Press the blue link that says "Repair phone". Do this without the phone connected and then follow the instructions given to you in the program.
