My 9790 is continuously rebooting by itself. It goes on for a few minutes, i enter my sim card pin and after a while it goes into a reboot cycle of between 4 to 10 reboots then it works for a while and then the cycle restarts. i've reloaded the software about 5 times in the past 3 months after getting a JVM error. even after the software updates it still reboots continuously. the Options icon has now disappeared from my phone. The "help" does not work i get an error everytime i "click" on help. i've removed most of my applications and removed the memory card. The device has a built in memory of 2Gs. So i'm sure its not a memory problem. Please assist its driving me insane. Nothing has happened to the phone to cause this problem (i.e. it hasn't fallen). My phone has a pin lock so no one but me could have used the phone and delted important apps.
