iPhone acting screwy
So this morning, out of the blue, my iPhone 4 starts giving me the "this accessory is not optimized for iPhone" message even though it isn't plugged in to anything.
What's weirder is that even with the sound turned on, it will not play any message sounds, rings, etc. and instead vibrates. Also, when I hit the volume buttons, the ringer window pops up, but the little slide at the bottom is non-existant.
Has anyone encountered this? I did update to iOS 4.3, but that was last week and I haven't had any problems with this phone before now.
