I'm sure this has been asked before but I wasn't able to find a relevant thread, so pardon my newbness with regards to this topic. I recently bought my wife a shiny new 15" MacBook Pro and I'd like to sync her iPhone to it, but of course iTunes wants to completely wipe the phone of music and everything. So, how do I go about this without losing all her data? Any pro tips? Thanks in advance for those patient enough to help!
