I am currently a T-mobile customer with two lines, one for my wife and one for myself. We want to pre-order the iPhone 5 and become Verizon customers. Do I just pre-order the phones and then port our numbers over after we have received them? I guess what I am asking is, do I need to give Verizon any kind of heads up when we pre-order that we will want to port numbers, or can I just take care of all of that once the phones arrive?
I know I have to keep my T-mobile account active until the numbers are ported, so I will definitely being doing that.
