Is it possible to port your phone book (not your phone number) from an ATT phone to a Verizon phone? I just added by husband to my account and got him a new number. His phone was a work cell provided by his previous employer (its still active right now). My account is Verizon and his is ATT. He has tons and tons of numbers and I'm looking for a way to port those over rather than manually typing them all in. His previous employer will be shutting his phone off in the near future.

We used backup assistant with Verizon but he doesn't have access to the ATT account because he is not the name on the account.
