Has anyone had an issue with their 3GS voice control headphone going nuts?? By going nuts I mean, this morning I'm listing to music while I am working out and my music would pause/play/pause/play/skip to next song/pause/play/voicecontrol on/off/on/off pause/play... etc So I unplug them and it stops... plug them back in and it starts again and So I restart the iphone and a few min later... Same thing again. I'll probably get them replaced but I was just wondering if any had an idea what could be causing it before I did.. Thanks!
