The story is quite humerous... I just purchased a used macbook pro with a month of apple care on it... Yesterday the screen started flickering... So today i called so i could ship it in (nearest apple store is 1 hour away), and as soon as i got off the phone with the guy... my iphone 4 froze (for the first time). LOL... Im running iOs 5... and im not jailbroken.... is there a way to unfreeze it without putting it in DFU mode, or letting the battery die???? Thanks
