Hello everyone, I am planning on getting my first iPhone when the 3G S comes out. I am currently a Verizon customer so i'll be switching to AT&T and I definitely want to port over my current number, since I have had it for over 5 years. What is the easiest way to do this? Should I preorder the phone on the AT&T website? (keeping in mind that I still will need my verizon phone active until I get my iPhone in a few weeks when they are released) Or should I just go to an AT&T store when the phone comes out and get the phone there and have them port my Verizon number over to a new AT&T account? Thanks!
