Awesome! I've been using standard #777 DUN with my U740 and now seem to have a little bit faster connection.
FYI, it shows up on your bill as minutes used, not data usage. The number shows as (777) 000-0000 on your bill.
I do have a problem though. I somehow wasn't able to connect while outside my home area (Seattle). I was in Minneapolis and tried connecting but got an 'Invalid Username' message. Then again in Louisville, same message. Connected fine when I got home to Seattle.
Anyone know why this might happen? I had to pay for airport wifi which I HATE doing. :|
