Recently, I used Spirit to Jailbreak my iPhone 3GS (Firmware 3.1.3) and due to a silly mistake I was forced to restore it. Unfortunatly I am recieving an error each time I attempt to restore. Or it just gets stuck on 'preparing iPhone for restore' the error code I got was 1604. I'm pretty new to this whole Jailbreaking thing but learn quickly from my mistakes. Any help would be much appreciated. 'edit, error code is 1604 not 1602'
