If I have a basic phone and upgrade to an Iphone would I need to activate it before selling? When upgrading it requires adding a data package is this added automatically or only if the Iphone is activated? If it is added automatically what do I do to ensure I am not being charged for data, on my basic device? I have read the phone has to be activated to accept the terms and conditions of the contract, but I have also read the terms and conditions are accepted when the order is placed,which is correct?
