UPDATE: I too did not do a factor reset, did not delete any apps, but simply set the phone to silent. When the update 1st appeared for me, I initially asked it to remind me later. I did this a couple times before actually doing the update. I plug my phone in at night, every night. The 1st night after the update, it was 2am (central time) when my phone began the wonderful DROOOOID reboot. Every time it started, I grabbed the phone and played with it, thinking I would see what was causing the problem. This happened 2 nights in a row. I have no newly installed apps, and I didn't play with the wifi, internet or cache. By night 3, I simply set the phone to silent and let it run its course while I had Droid-free dreams. I've been using my phone since then with no issues at all.
