All I did was move apps to my sd card this evening. I started to play a game and it froze. When I restarted it all that was showing at the bottom was just the "Applications" button. No "Call" or "Message" etc. No idea what happened. I haven't rooted it or anything like that. And yes, I tried restarting (failed IT joke...) ::EDIT:: The icons just moved to my applications list. Weird.
