Apple’s DRM technology used throughout the iTunes store for music and now applications as well. Fairplay allows you to register up to 5 computers and unlimited iPods/iPhones synced to those computers. So… it should be easy for my wife and I to share iPhone apps with each other as long as both our iTunes are authorized to use them. All we need to do is authorize both accounts in both computers and re-download the apps. This could work in Windows, but why would I right?
Here’s a step by step tutorial on how to do it.
I have 2 Macs, 2 iPhones, 2 iTunes accounts.
I used one account to buy a game, and another account to buy another one. The goal is to have both games playable on both phones legally with no hacks.
Have each computer be authorized for both accounts. Re-download apps on 2nd computer with 1st computer iTunes account.
Step 1: Authorize Computers
I step into my friend’s mac, launch iTunes, log out of her iTunes Store account and log in with mine.
