Sync iphone to "new" computer
I have a iphone 3GS and used to sync it with my pc. But last month it crashed and had to do a reboot and lost all my files, music, photos, etc. Now I want to copy everything to the computer but when I try to do it, it just wiped off the songs and apps from the iphone (but of course i clicked "revert"). I need to copy from iphone to itunes since I'm considering get the iphone 4 and want to have the 600+ songs, lot's of apps and that.
Please, it's driving me crazy since haven't found an answer for this. Thanks for your help!!!
3gS, iOS 4
