More often than not, when I reboot my phone it will hang. It's not consistent...but it happens enough to be really annoying. When I press the power button to reboot the phone. Sometimes, the white M will go dim...and the phone will just sit there. Sometimes, the phone will just stay on the white M. Other times it will go directly into bootstrap loader. I have to do several (like 5 or 6) cycles of pulling the battery and rebooting the phone to actually get the phone fully booted. Anybody know what this could be?
