I shoul have my new iPhone by next week and I am planning on porting my number from Sprint to AT&T. My contract with Sprint is up and I know once I port my number I will need to call Sprint to close out my account. My Question is: How difficult does Sprint make this process. I figured since my number is already ported there is little they can do to keep me. I am wondering what kind of phone call this is going to be... 10 minutes or 1 hour being transfered from one person to another.
