Just make sure you tell them you want circuit data and not packet data. They try to sell you the packet data option so they can charge the hell out of you. The packet data is for dialing into their isp to get email, sports scores etc. If you do not get the circuit data it will display call failed every time you try and connect. The link I used to get the drivers is http://www.motorola.com/iden
Make sure and follow the install instructions to a tee and do not worry about the Mirco junk warning of Not Digitally Signed Drivers. Good Luck!
Two wire hook up, three wire f**k up.
