Hey guys. I'm new here so I don't know if this has been discussed already so if it has, sorry! Well I bought an iPhone a while back and my friend hacked it so I can use it with my T-mobile service. Everything went well and I wanted to put some of his music from his computer on my laptop. This is where it went wrong. I created playlists so he could just sync it to his computer. So now my iPhone is synced to his computer and I can't do anything like add my stuff on it from my computer. And actually, my iTunes doesn't even recognize my iPhone anymore! What can I do? Is there a way to unsync it from his computer? What happens if I try to restore the iPhone and start over? Will it turn into a "brick"? Please help! Thanks!
