ok, it doesn't give the apn. all it gives me is to edit the name of the connection, then below is user name and password which i don't know what for? if i press next it gives me the proxy and ip address. i found it before and now its gone.

let me know if i am doing something wrong?
settings- internet connections- connections- tmobile intermet- edit- then i get what i explained above? any idea?

i also used fapn. it makes a connection but if i want to edit i get the same problem?

am i looking in the right place?
