Rooted phone never had a single reboot in the 2 months i had phone. Today out of the blue phone froze and rebooted I have had 4 reboots in the past hour. I NEVER HAD A SINGLE REBOOT BEFORE TODAY. Phone is rooted. I have MR2. I haven't flashed any new roms, radios, or kernals in the past day or two. What is causing this?
