I updated OTA as soon as I found a wifi spot. Experienced absolutely no issues, as a matter of fact I was a bit surprised that it only took about 19 minutes from start to finish, sitting in the parking lot of a hotel using their wifi connection. As far as a battery fix, I'll find out today. I didn't really monitor the battery after update because I wanted to go ahead and let the phone go ahead and "die". So I could have a 0-100 charge.
Special K, cause I'm special, duh!!!
