Hi. My Ipod Touch 2g Wont Go On The lock screen when turning on. since it is jailbroken, it changes the start up with a little skull since i used greenpois0n to jailbreak. Before this happened, i was deleting things from cydia and a box popped up saying that if i deleted the thing cydia might go away and i pressed it and when it was finished, cydia was gone. i tryed to download it again from loader but it said it was already installed and i searched cydia but nothing came up so i guess its gone. well when i turned off my ipod and turned it on again it just froze on the skull face. please answer!
