I need some advice on how to solve this issue.

i have a rogers bold on AT&T's network i love the phone. i have the latest software .167 my problem is as follows my BB reboots at least 5 times a day the times it does it is when i get into my car the bluetooth will activate and then after an email comes in or i go to a program the device reboots. This happens in all my cars with blutooth. Now i can be sitting at my desk and click on a program to open or an email and when i am finished the device will reboot. not more the 5 min ago i plugged my earphone in and when to play a song and it rebooted. I need help on what should i do. i dont know what app or setting is causing it. th funny thing is that i can go for a few days with no issues and then it just starts up again. I need some expert help

I would try the Media Card issue first. Do you have a media card in the phone, if so, try this:

8320 restarting after OS 4.5 upgrade

If not, or this doesn't help I would start looking at the third party apps you have installed.

thanks its not a media card issue it happens with or without the card. i am going to remove all the apps and see but i think i need to do a wipeout and reinstall i just need to remember how to do a clean install.

See this post for a walk through on the JL_Cmder tool.

thanks.

I had the same thing with the one I got from Rogers... did a quick swap of devices and no problems since. Then again I had the choice of returning the device within 30 days so a swap was not a problem. Don't know if you have that option.
