I have my own iphone 4 and my wife has an ipad 2 and will be getting an iphone 4S. Currently we use just one appleID between the iphone4 and the ipad to share apps. When my wife gets the 4S we'd still like to share apps by using the same appleID however I'm afraid the iCloud sync will interfere with our 2 iphones. One of the features it touts is being able to start something on one device and finish it on another. If I started a book on my iphone will it also keep track on my wife's iphone? This would be a bit troublesome as we'd like to keep these types of things independent. We still like the idea of other things like the photostream being shared but not everything. Does anyone have a solution for this or how exactly this will work with our setup? thanks.
