Alright this just happened about 3 minutes ago. I'm studying in my room, reading a few chapters of a book for tomorrow's class. My iPhone is asleep, sitting on my bed. Headphones are plugged into it (the regular Apple ones), but it's not on, and I haven't used the iPod app in days (I typically use Simplify Media, as I could never fit my music library on my phone). Anyway, the screen is turned off obviously, and since I haven't touched it for at least 20 minutes, the screen lock is on. Well out of nowhere, the screen turns on, and the phone starts playing a song from the iPod. The keypad lock doesn't come on, and the screen just says "slide to unlock," but the song is playing through the headphones. A little creeped out... has this happened to anyone else?
