So what seems to be happening is my iphone is kind of acting by itself. Mainly it's the home button, like when I have it locked the screen lights up, or it exits applications, or switches between the home screen and the search screen. It also showed the 'this accessory is not made to work with iphone, would you like to turn on aeroplane mode etc' message once, and a couple of times the screen has gone dark (but not black) while I've been using it. Bear in mind this is all in the last.. 45 minutes. I tried resetting it, and also cleaning out the port at the bottom. I'm not sure what else I should do, any advice? EDIT: Forgot to mention it's a 3G.
