I had the same problem
I have an iPhone 4 I bought it in June 2010. Couple days ago I had the same problem and took it to a not so "genius" they said they couldn't do anything because it's out of warranty and I would have to pay $150 to swap it out. A minute later he said I have to pay full price because when I went to the apple store on September, they noted that "this phone has been jailbroken repeatedly. do not service this device" I only jailbroke it once. So i'm going to have someone open it and fix it, sell it, and buy a samsung galaxy s2 which is 10 times better then a stupid iPhone. I loved iphones but after I went to the Apple store everything just went down the drain.
