I've had AT&T for about ten years, but recently moved to San Francisco and AT&T is horrible here! Everyone I know who has Verizon in this area is very happy with the quality of reception and availability throughout the city. When I ordered my iPhone I opted to port my current phone number with AT&T to my new Verizon iPhone 5. Does anyone know when that porting of phone numbers takes place? Is there something I need to do upon delivery to make that happen? Thanks!!
