When moving from a Sprint iphone 5 to a 5s that will be activated on t-mobile, is it possible to turn on the 5s, login in with Apple ID, and load iCloud data on the phone (photos, text messages, contacts, notes, email, etc.) before inserting the t-mobile sim and activating the device? If the iPhone 5 is used for another day or two before the iPhone 5s is activated, will iCloud update/duplicate the data (text messages, etc.) on both devices?
