i used customize to revert to my original theme from a vista theme. when it was reverting, the screen kept flashing and customize applied the original theme twice. then i reebooted my ipod and came to a flashing apple logo. now when i open apps, the screen becomes unresponsive and when i lock my ipod, the screen dims and doesnt turn off. also, i set my boot screen to verbose or somethng so i can see scrolling white text. it says stuff like "wrong file block (it should be 10343 instead of 10342" and stuff like that. how do i fix this without restoring for the 5th time in a month?
