I just bought a Macbook, and I have an iPhone 4s and I was wondering how I could sync my apps without losing the app data? I already have my music transfered onto the new computer from the old one, but I'm unsure of how to do this with the apps and their data. I copied all the backups from my last computer to my new one but I am still kind of scared to sync as I don't to lose any of my saved games, etc. Thank you in advanced.
