hey i was wondering if it is always possible to go into DFU. I have had countless problems with my ipod and was wondering if it ever breaks during these if i could DFU it. So here are my q's--- Can i DFU when my ipod- is booting up? is on? is downloading from cydia? when the screen just goes black when safari is still running (can see status bar) When my ipod crashes and i reboot it?
