Oh yes. That snafu cost me $800 on Sunday. Had a 0630 airport showtime for my son's flight. My wife and I both set our iphone's so we would have back-up. Stupid idea. When we woke up at 0640 it was like a scene from Home Alone. Since I knew we couldn't make it, I just called the airline and rescheduled. Gotta love Apple's technology. That $200 iPhone 4 I got my wife for Christmas now costs over $1000.
Lesson learned?? 2 alarms from 2 different sources--always. (I'd NEVER had a problem with my 3GS before) Oh well.
Happy New Year folks. Fly Safe.
