I got a new hard drive for my mbp and I just set it up as a new install and when I plug in my iPhone the music shows up I can play it, etc...but I cannot add new music. The computer wants me to erase the iphone and restore it. I do not want to do that because I have a lot of text messages on there (Over 2 years old). I do have the old hard drive that I have not erased yet, is there anything I can do so I can have it setup on this computer?
