Hey there! I'm just quite tensed right now because I had downloaded iOS 7 through iTunes (Latest) and then hit the "Update" button, and then I could see the "Connect to iTunes" logo on my iPhone 5 and the message on iTunes read "updating iPhone" .... and that took about 5 minutes and after that I got an error "Cannot update the iPhone. Unknown error occurred (4005)" .... and since then my phone is stuck at the connect to to itunes sign ... I tried to hard reset it or take it to the recovery mode (Power + Home, release Power keep Home pressed), but nothing is happening... HELPP PEOPLE!!!
