  1. DENNIS is right. I needed this address book. thanks men.

  2. Not that we don’t appreciate the new apps but I think pretty much everyone’s phone has this with the contact details.

    • Actually iDEN phones don’t have anywhere to store information like snail main address, birthday, etc. The contacts app is restricted to phone numbers plus one email and one IP address.
