Ok, so this is happening as I type. The iPhone is ringing off the hook and won't stop!!!! The only thing is NOBODY is calling me! It shows nothing and has been ringing for about the last 5 minutes. It then freezes up and goes back to the lock screen but it won't stop ringing. Obviously I'm going to reset it, but this is the second time the crazy thing has done this and I'm not sure what the deal is. Should I go in to the Apple Store and get it replaced???? The other side of the problem is that my speaker will spontaneously stop working and won't ring for a call or when I'm using it for music or Apps. Any advice on this would be great!
