I recently did some updates to my phone through cydia. After installing some of the updates (BossPref, IpodMovies.info . . Cant remember the rest.) my phone started slowing up a bit when switching screens. Now when I click on the phone Icon it shows up with no writing under the dock icons and goes straight back to the menu screen. Obviously it will have something to do with the updates that I done. Any idea of a fix. I HAVE SORTED THE PROBLEM. UNINSTALLED AN APP CALLED KATE, RESTARTED AND FIXED.
