My iPhone 4 (4.1 firmware) has started rebooting constantly, never getting past the Apple logo.
Sometimes the connect to iTunes logo comes up, and plugging it into the PC tells me iTunes has found an iPhone in Recovery mode, but I cant get it to stay on long enough to Restore, it reboots all the time.
I thought about trying DFU mode, but I dont know how to get it into DFU mode when its constantly rebooting.
Help appreciated.

I eventually got it into DFU mode (I knew because Windows said it found new hardware Apple iPhone (DFU mode), and the screen was black).
During the 15 minutes it took in iTunes to download the 4.2.1 update, the phone didnt reboot at all, so I though great.
I did the Restore, and everything went as it should during a Restore (white progress bar on iPhone, iTunes saying the phone had been successfully restored at the end), but once it was done the iPhone rebooted and went back into the constant rebooting problem.
Any more ideas?
