I am also having ramdom reboots on my brand new Bold 9650 with OS 6. The reboots first started on my Tour and they told me the device had gone bad and I needed to upgrade. I upgraded to the Bold 9650 but the first one had the 5.0 latest version on it. That phone rebooted as well. After doing a wipe and starting from scratch the phone still kept rebooting so I took it back to Verizon and they gave me a new Bold but this one had the OS 6 and this one is also doing the same thing. At this point I really can't believe that all three phones were bad so I know it has to be some kind of glitch but my reboots happen whether i'm using the phone or not. They happen a lot while I'm using the trackpad. They had told me that my memory card might be the problem with my first Bold so I did not put it into my new Bold with the OS 6 and it didn't matter because the phone was rebooting anyway so I knew it was not my memory card. I did not load any applications to the OS 6 Bold and STILL the phone reboots. I really like the Bold and the company I work for has the Enterprise Server so I want to stay with a BlackBerry but at this point the reboots are just too annoying. I am hoping that someone out there has found what may be causing the problem. I hope to hear from someone soon.
