You will not get your upgrade back right away and it'll take days if not a week to get it back. That's because the carrier is very slow to get that done. Especially if it's AT&T - last time it took them 2 weeks to get mine reset and I left them because of it.
Ok well what do you think? The charges have been made to my card despite the wrong billing address...will that be a problem slash can I change it first thing tomorrow once Apple is accepting calls again?
Everything else is correct and I got the shipping address confirmation e-mail.
