Gday all. I hope this hasnt been asked before but I couldnt find it looking around. I drowned my Asus Laptop a couple of days ago and I bit the bullet and bought myself a iMac as I don't need a laptop anymore. Now the problem is I got all my music on an external hard drive which I can access but I want to be able to sync up my iphone 4s to the iMac with out destroying the data or apps on it. How do I go about it without the phone being wiped clean? Thanks in advance. Stick.
