Flashed Sapphire 1.1.1 two days ago, using the latest 1Ghz LV kernel on the newer official site. At first, I was impressed, but now, I've experienced more spontaneous reboots in the last 48hrs than I have in the past 8 months. Seems to be more frequent when the GPS is turned on. I'll start Nav, turn on GPS, the phone will pause, and then reboot. Other times, I'll have GPS on and never start Nav, only to have the phone reboot when I slide it open to respond to an incoming text or email. Its also rebooted with GPS off, a text/email will arrive, I'll slide open the keyboard, the screen won't turn on and then the phone reboots.
Never had this problem with 1.0, didn't have a chance to flash 1.1, and did a fully data&cache wipe before moving to 1.1.1. Any ideas? Or should I just roll back to 1.0?
