Not to scare anybody, but I just wanted to report what happened this morning, after I upgraded via the manual way (update.zip) last night.
I looked over at my phone this morning and it was just doing a loop between the droid "Eye" , and the driod logo (that you see when it starts up)...just over and over again. The phone was very warm. Thankfully, when I pulled the battery, all was well and it restarted fine.
I haven't installed anything new, so I just find it a little weird that I just updated and this is the first time that this has happened.
Just a 'heads up.'
