Still haven't received my preorder. Ordered a white for the wife and a black for myself. Wondering if I can use mine to set up appointments, or other notifications and send them to my wife's 4s and have them sync? If not a standard option, then what if both phones use the same apple ID? Can e both just add appointments and notifications, notes, etc. and sync them through the cloud? It would be great if this were possible, because our schedules are complicated with work, kids, etc, and our communication on this isn't always what it could be. Seems like this feature (or option, anyway) would be helpful. Any thoughts?
