So my buddy just got an iPhone 4 and previously had a 3GS. He hasn't synced his 3GS to itunes in a VERY long time. He just bought a new laptop and wanted to know if he can copy apps off his old 3GS into a new itunes on a new computer. Then once those apps are saved on his computer then be able to sync them to his new iPhone 4. The reason why i'm asking for him is because i'm the one who will probably do it and i've never attempted this before. I know I should probably change the itunes option so it won't sync right away before I hook up the iphone. Beyond that i'm not sure how to go about the rest. Any help would be appreciated.
