Update... Well, my phone didn't reboot itself at 2am today. Here's what I did... Yesterday I removed all apps that I haven't used in quite a while, including some system ones. Ones that might have been a problem were a v1 copy of find my droid, an old system panel lite, and an old battery meter. Ther were other apps I also removed, but too many to list. And, I did turn on wireless. Kind of surprised me that it was off since I normally have it on. Anyway, no reboot last night, hopefully the issue is solved for me.
