Hey Everyone, I've noticed this on every iPod I've owned since the first shuffle but never really cared all that much until now. I have a Macbook Pro at home with which I've synced my iPhone, but I work on a Mac Pro at the office and would love to be able to sync there as well but when I tried today I was give the 'this iphone already syncs with another library, would you like to erase everything and sync here instead' message. This isn't preferable - I'd rather not erase anything but just be able to add. Is there a way to do this at all? Am I crazy? Also, I love my iPhone! VERY happy I got it! Oh, one more thing. Anyone know the best place to find great iPhone wallpapers?
