(MAC TO WINDOWS) Hi all! Please help if possible. I have an iphone 4. I have a mac. I gave it to my friend and he has windows. He put in his micro-sim in my phone and i did a full restore on my mac. I then plug it into his windows laptop to back up from his old iphone but the phone doesnt show up in itunes?! If i did a full restore on the phone should windows itunes recgonize it and he put all his data on there from his old phone (iphone 3g)? any help is appreciated. btw when i plugged in his old 3g his itunes recogonizes it right away. Thanks!!
