i know i know...its an iphone 4s, but not until now has there been a problem. headphone jack produces sound...no problem there. no its not the mute ringer little orange button. it is updated to latest os. its never had any problems handling the new os. its a about a half second slow when i open an app, but that is the only difference ive noticed when comparring it to my newer iphone. anyone have any other ideas besides a hard reset? thanks in advance.
