I have an iPhone 4 currently syncing with my windows vista desktop. I would like to get my iPhone 4 to sync with my new macbook pro. I know of the Transfer Purchases feature in iTunes. My question is, does this feature transfer also the game data along with the actual app in iTunes? Does anyone have a guide to successfully get my phone syncing to my macbook pro without losing all my app data, contacts, etc. I'm mostly worried about the game saves for my apps.
