www.alltel.com in gateway and change the alltel to mycricket in server address. I got things done. but getting it back into a cab and working has become a hick-up. Was going thru it agian when notice popped up you replied. I get stuck, I'll post my progress and files if you can help. Not sure what I am doing, but positive on what needs to be done and what edits are needed.
