Thankyou, i think this might just be my option. Didnt think of that. Was hoping for a quicker method.Are you running the stock launcher? Try wiping the cache partition: https://support.t-mobile.com/docs/DOC-16654
If that doesn't work, and if you don't mind setting up your homescreens again, go to Settings>Apps>All, select Launcher (or whatever the Sony launcher app is called), and Clear Cache/Clear Data. When you go back to the homescreen, it'll be blank, and you can start setting it back up again.
