I installed summerboard 1.1.3 and switched to the time machine theme, then I exited summerboard and got the normal circle that spins in the center while it updates. However, the circle kept spinning around and around, not locking the ipod like it usually does and then changing the theme. I rebooted my ipod and now I get just the apple logo and the spinning circle, no springboard/summerboard launches at all. However, I can still sync my ipod via itunes and ssh to it. Is there any way to fix this without restoring and loosing everything?
