Answer to: iPhone completely dead, wont charge, wont turn onsystem may have crashed. it happened yesterday with mine. took to apple store and they said the software "freaked out"(a technical term i suppose) and they restored it but i lost all my data and pictures that i had not backed up in a few months. It sucks to say the least. So, you need to back up your data every couple of weeks or else you risk what happened to me. Now i know.
