T Mobile data or T Mobile Internet
 

Hi all, I just received a new T Mobile Dash 3g. It will take a little getting used to but I like it. I have a question about the Internet Connection Sharing application that is included. For the connection choices there are two choices the first says "T Mobile Data" and the second says "T Mobile Internet". What are the differences between the two and which one should I be using?
thank you
