I also have do random reboots out of nowhere. This is my first android unit, so I still dont know many things about it, have it since 10 days. What really is getting on my nerves: if I turn off the phone, in 50% of the cases it will turn off the screen, but the keyboard light stays on, and every ten seconds or so the Android-logo appears on the screen. seems to mike like its trapped in a rebooting sequence. Only way to stop it is opening the back cover and taking out the battery. then its normal again.
