I got the tour for my sister on Sero, you don't have to do anything. Just let them add the phone to the account and don't let them do anything else. Than, call Sprint BB tech support and tell them your missing your internet and to please send the service books. It depends on the rep, sometimes they don't know how to do it and are a waste of time, so call back until you get someone competent. Once you get the service books, everything else should work like the BB messenger etc and you still pay the same $30 charge!
