Non-consumable in app purchases in iOS. Do I need a server?

Question

I'm implementing an iPad game and want to allow the player to buy an extra map. Do I need to implement a server and store that purchase so that I can handle the user changing to a different device or does the StoreKit handle it automatically for different devices? That is if the user purchases the extra map on device A using his username and then installs the game on a new device B with the same username do I need to do something special or will the StoreKit remember the purchase so that he won't be billed twice?

Answer 1

No server is really needed for this - make button for "restore purchases" and user will be able to get all his "extra maps" on every device. Nice framework to implement it.
