One day I dropped my 16 GB 3G, It landed SO hard on the kitchen tile one day. It landed PERFECTLY FLAT on its face. I picked it up, the screen went white, then Black. That was the last time I ever saw my baby light up.
Luckily for me, There was absolutely NO physical damage. I walked into the Apple store, Played dumb ("I don't know what happened, It just wouldn't turn on!") I walked out less than 10 minutes later with a brand new one costing me zero dollars.
Was yours Jailbroken?
