My bottom 2 rows are completely frozen. There were working fine at the gym (i was selecting music at the bottom left of the dock) and when I left, I tried to go back into the music menu, and found that the bottom two rows of the interface will not work at all. I've tried restarting, plugging into itunes and charging, and even tried to rearrange the icons but it won't let me drag down to/from the bottom 2 rows.. I realllllly really don't want to have to force restore and jailbreak again and then put all of my music back on....help!?
