So, there you have it! I hold the world record for battery life on an iPhone 4!!

BTW, don't let the time and battery percentage throw you. I took a screen grab of the Usage screen first and E-mailed it to myself. It was about an hour later when I though to also E-mail myself the General settings screen. And, yes, I was in different locations for each screen grab (thus, the difference in signal strength).
