Okay, here's the deal. I recently bought a Mac after I had already bought my iPhone 4. I had to sync my phone up to my family's desktop PC, but now my Mac has all of my information and music that I'd like to sync to it, and it's much more convenient to me to be able to just sync to my mac instead of my PC. Also, I want to get as far away from PCs as possible haha . I was just wondering if I reset my iPhone to be able to sync up with my mac whether or not I could re-download all of my paid apps again for free.
