...and it doesn't shows up in? iTunes or windows explorer. The phone has a firmware 3.1.3 installed onto it and the baseband if i remember correctly is 5.14. Can somebody please tell me how can I fix it? It's not responding to the usual Home key and simultaneous wake/sleep press. It shuts off when i press both together (w/o showing any intermediate screen for shutdown confirmation)and then if i press wake/sleep, it straightaway shows me the apple icon that stays there for about 45 min, before it self restarts.
