OK, odd problem. Friend in my family plan who has a 3GS running 4.2.1 (happening past couple of months since even before 4.2.1) is having an odd problem that her phone starts playing the iPod at random intervals. She's good about locking her phone, but the problem still happens. No alarms are set or marked on. It goes off in the middle of the night while plugged in on the night stand. Has gone off in class a few times. It's not playing alarm tones; it actually is starting to play songs. She's restored the phone a couple times, including once without restoring the backup. Seems to do it regardless of if the silencing switch is set or not. She took it to our town's AT&T store, and they referred her to call Apple. Apple wouldn't talk to her and insisted on her paying the phone service fee. The phone is still within the 1-year warranty until May but the 90-day phone service is expired. Planning on a 50-mile each way trip to the Apple Store to get it looked at, but does anyone have other alternatives??
