Have ATT 4S and want 5S Verizon gold 64. ATT says I'm upgrade eligible. Have an Android phone (Galaxy S3) and iPad on Verizon Plan and want to add second phone to Verizon plan (new Verizon 5S would be the additional phone.) Since the upgrade is with ATT, Apple said just order online for Verizon phone and bring it to Apple Store where they can transfer my ATT phone # from my 4S to the new Verizon phone when it arrives. Will that work?
