I don't think t mobile have such info anywhere
I have been talking with them on the phone like forever
but they don't even know the device (770) they have been connecting me all kinds of departments... So I thought maybe writing to a forum would have someone that experienced the problem and could help me
Some of us are much more experienced then the best expert in t mobile

I have installed the Latest update (from nokia europe) and it just connected thru, internet2.voicestream.com
and nothing else needed it is connected and I was waiting for a very slow connection thru cellular network, but I'm really impressed with the speed... Thanks for all your help...
