I am using an ipod touch 2g on 4.0.2 software/firmware whichever. I tried for about a week to fionall yget my itouch jailbroken, and it screwed up my itouch. cydia has a white icon, and everytime i load it it automaticaly says "error refreshing data". my safari browser wont work and neither will my app store or youtube. how do i do this correctly or at least return my ipod to normal? all my apps were deleted too
