Say for example there's 3 people. Person 'A' has an app that person 'C' wants, while person 'A' has another app that person 'B'&'C' want. Can person 'A' transfer these apps without any memory wipes or repercussions, and would the apps act as if they were bought from person 'B'&'C' as in for games to connect for Multiplayer and so and so forth?
Another question I have is what are the means to transfer data and purchases, is the only legitimate way via iTunes?
(I know it's not very detailed but I do appreciate any answers that can help clarify because I bought several of the same apps on different IDs and I'm hoping I can unify them)
Also, is there a limit to the number of accounts that can share an app or is it limited to one per account? Sorry to add on, but can anyone copy and paste, explain or link the rules and regulations that explain and could help with my problems?
