Love Gummynex, been a user for a little while now. I flashed 0.7.6 earlier this week along with the new leaked FA02 radios. My phone seems to have some issues with crashing randomly. This morning I just dialed a number to call out, it rang, then the phone rebooted.
The other times seem to just be random lock ups. The other morning I had messages (blinking LED) when I woke up, however the screen would not turn on.
Lastly, this seems to be fairly consistent, and may actually be an issue with the built in tether, but anytime I tether, and have the phone plugged into AC, when I am done tethering and go to turn it off, the phone will eventually reboot as well.
Thoughts on looking into these more? Of course none of them are "triggerable" or easily duplicated, I'd say the tether thing is the most predictable.
