I've had my iPhone 3GS since October '09, so it's about a year and a half old at this point, and I'd never really had any issues with it until a month ago. It started turning off with 10% battery. Then 20%, 40%, and this morning it shut off with 74% battery left. It had been off the charger for maybe an hour, and I'd been using the camera to capture video. When I try to turn the phone back on after it so rudely shuts itself off, I get the silver apple, and it stays there. I think it eventually turns to black, but I've stopped trying to turn it back on since it doesn't do any good. Am I the only person who's had this issue?
