Hey guys, I went to play one of my games, f-sim, and now it won't turn. Like when I tilt the screen. Even my texting, pictures, and internet don't tilt when I turn the phone. Which is ordinarily great news because I hate landscape mode, and never really use it, but it sucks that my games don't work. Is it broken, or did I lock it somehow? WIll apple replace it, or am I screwed? Its an iphone 4.
