So disappointing!
We waiting over 30 minutes to be seen at the "genius bar" for my boyfriend's phone that has seen better days but really was working fine until just going out yesterday. They barely looked at it and said they couldn't do anything to salvage any of the data in the phone. They just tried to sell us a new phone.
We took it to one of those repair shops and within a few minutes they said it was most likely a battery issue. $45 bucks and an hour later, the phone was as good as it was the day before.
Genius bar is a joke! Go to a real repair shop.
