I thought having a curve that offers wifi will automatically let me browse trough the internet when i m at home in my wifi range. But so far it dosen't. I don't get it. It shows the UMA wifi connection, but everytime i go into the broswer it just sends me the message that :i m not currently subscribed to a tmobile 2go plan...." Shouldn't it still work, since I m using wifi? Am I doing something wrong???
