We have 3 devices, my iphone 4s, wife iphone 4 and an ipad2 which we both use. We currently share the same apple ID for purchases. When I activated my phone i used that same ID for icloud. What I would like is to share calendar, apps, books, music etc. but for photo I want it inly to be on my phone or have some control over it, which pics I want to show up on my ipad and her iphone etc. I don't know how to set up icloud so that I can keep it separate.
