Hi guys, All of a sudden my girlfriend's Nexus One is rebooting somehow. She fires up her phone, it boots just fine, after a few seconds when everything is loaded, u can scroll thru the menus etc, it seems to reboot, but real fast, the animation comes up, and 2sec later the home screen is visible again. It keeps doing this. Any ideas ? The phone is not rooted, no custom rom, just a few regular apps form the market installed, nothing fancy.
