Rebooting issue (CM7)

I've had CM7 for about a week now. I'm starting to have issues with my phone rebooting. It seems to happen when my phone goes to sleep. I'm running the 0728 mod. CPU settings are still at 600 Max. I reflashed yesterday and am still having issues. I am out of my normal area but not sure if that would cause this issue or not. Any help? Please??

 

The only thing I did was customize my home screen (wallpaper, icons). The apps I installed ran for a week with no issues. I the Atlanta area (I'm on Metro) and my phone started rebooting. It started when I installed Smart Keyboard and changed the lockscreen style but I have since removed the app and reverted the lockscreen to default.

 

The reboot problem seems solved. However I am now missing calls and the Roaming Indicator Off notification is on. I have flashed MetrOff 3 times. Suggestions?

 

Just tried it and it didn't remove the roaming thingy. The only thing I can think of that I'm doing differently is I'm dling directly from my phone instead of using my PC. Other than that I hold the power button, reboot into recovery, install from zip from SD, choose zip, MetrOFF, back out to main menu, reboot. Am I missing something? I've been using the link on the Wiki.
