Ok, just wanted to clarify something. Ill do an example.. example: I have an iphone, I purchased Doodle Jump back in January on it for 99 cents through the iphones app store (on the actual iphone itself). I have my iphone synced to a imac. Now, I deployed overseas with a company Dell laptop, and just got my ipad in the mail, I have been buying apps through Itunes on this laptop in preparation of getting the ipad, so i have like 30 apps (I am logged into the same account name on this laptop that I have always bought stuff with on my iphone). Ok, now I get my ipad, and sync it up and authorize it for this pc and all the apps that I downloaded on this dell come through just fine. Now, here is my dilemma. I want to see if I can get doodle jump on this ipad. Its 99 cents. If I click buy in itunes or on my ipad, will it realize that I have bought it before on my iphone or will it make me buy it again since I am on a new device, and I have never backed up doodle jump on this dell. Anyone?
