I switched to an iPhone, ordered it Tuesday and said backordered, but now just says ordered in process. Well anyways, I have Sprint(still do until I receive my iphone) and I want to know when should I cancel my account? Should I wait until I receive my iPhone? Or wait until the day I receive my phone? Also, will I have service as soon as I activate my account, or is there some down time I have to experience because my old account needs to be canceled first? I know this is all worded kind of weird, I appreciate any help, i've never transferred my number before.
