IOS – Does iTunes in the Cloud apply to Movie Rentals

For some reason when it syncs, it sometimes only remembers the iTunes information and doesn't read the device information. So you may find that after syncing it will deleted apps you'd installed and install apps you'd deleted. It's very annoying. To get around that, I have set my devices to not automatically sync when plugged in. When I do plug them in, I right click the device name, click Transfer Purchases, and after that has been completed then I sync.

Firstly, you must bear in mind that each In-App Purchase is uniquely associated with an Apple ID and that there are different In-App Purchase types:

• Consumable - You need to purchase these items every time you want them, and you can't download them again for free.
• Non-Consumable - You purchase these items one time, and you can transfer them to multiple devices authorized with the same iTunes Store account.
• Non-renewing Subscriptions - You can purchase these items again after the subscription period ends.
• Auto-Renewable Subscriptions - You can purchase these items with different renewal periods.

There are, therefore, differences in the way the availability of the product is handled.

As stated on Apple's iTunes Store: About In-App Purchases:

You can't sync or transfer non-renewing subscriptions and consumable In-App Purchase to another iOS device or Mac. You can transfer non-consumable In-App Purchases and auto-renewable subscriptions to another iOS device or Mac authorized with your iTunes Store account. For example, if you transfer a game from an iPhone to an iPod touch, only the game levels will sync, and the extra ammo and experience points won't transfer.
