Can anyone help me out of how to use internet on an old AT&T (blue)? Recently I received an unlocked Samsung Black Carbon (SDH d900), and I want to use my old AT&T in it so that I can use uninterrupted internet services on it. Being a business man I have to share a large number of MMS on a daily basis. Therefore I would like my new phone to solve this problem of mine. Is it possible for me to get this setup, where I can use internet services on my AT&T (blue)?
