Hi i'm new to the forum, but what happend was my iphone kept switching itself off and to switch it back on it had to be reset (hold home and sleep button) and sometimes it would work sometimes it wouldn't. So to combat this i thought i would update it, it was version 4.1 and updated to 4.3.3 however just before it finished the iphone reset itself and it's now stuck in dfu/recovery mode (itunes icon and usb, sorry i dont know which one it is!) however every time iI connect it to the computer it resets itself, and this just keeps happening. Pleaseeee help me! It would be much appreciated!
