So here it goes... It's mine and my brother's intention to go pick up iphone 3gs on July 11th. He currently has an iphone plan with his work, and I am in a sprint contract with my father that ends july 1st (thank god). Our plan is to both get new iphones and give his old one to our father who isn't quite the tech nut we are. For the record, my brothers current iphone is jailbroken. My intention is to set up a new family plan contract with my dad and I. Me with a new iphone, him with my brothers old. My question then becomes, How would such an activation work? Since the old iphone was always activated in itunes, how would we put both on the same plan? Does it matter that my brothers iphone is jailbroken? I know we lack solid information on this, but if anyone has a current situation that may be similar, such as having a family plan that has an iphone on it, along with a different phone. Im just curious how that set up would work. do you activate the regular phone in store, and then add the iphone to the account when you get home?
