My mom's first smartphone, iPhone 4 8gig, is set to be delivered tomorrow. It pretty much went through all the annoying things that everyone's 4s' did, processing for days etc. But it's shipped and all set to be here by 4:30 tomorrow and I actually have the day off to get it and set it up for her. One question for anyone who has ever ported a number. How long does it take from the time I go to activate her phone to port her number and cancel her other line?
