Hi folks, I have a brand new Vzw iPhone arriving this Friday, ready to replace AT&T once and for all. Oh, also, my current phone I guess... Here's where things get a bit tricky. I ordered this phone as an upgrade to an existing, currently unused line on my family's vzw share everything plan (don't even ask). Meanwhile, I have my own AT&T account that I want to port my number from onto this new phone. I've heard dire warnings about not even turning on my new phone until I initiate the transfer request lest my old vzw number become tied to the sim, so I'm turning to you folks here on the forum: can someone please give me a stepwise guide on how the heck to get everything set up? Thanks!
