If you are with AT&T your TOS strictly prohibits tethering your 9000 as a modem. They want you to pay them $60/month for the privledge. If you rarely do it you MIGHT get away with it but they can catch you and if they do they will charge you big bucks. Lots of people do it. In an emergency to check an email or a website I wouldn't worry about it but if you do it often you are asking for problems. YMMV
