I was working out this morning listening to a radio station streaming on my iPhone 4 then I heard a song from the IPod and the streaming was gone. I checked the app and it was still streaming and the IPod app wasn't even active in the multi-task area. I had to open it and then stop the music. I thought it was just a fluke then it did it again and the voice command was open. I rebooted but kept working out and when it started the IPod started again even when I didn't have anything going on. It seemed to do this every time I put it in my pocket. When I got home I restored it just in case. It did it again. so I made sure all the apps were closed and it hasn't happened again. By the way, it only did this with the headphones in no other time. I can't recreate it now so I think it is done with this freaky issue. Has anyone had this happen?
