I know one of the local mobile phone companies sell a little module that is designed to let your laptop get on the internet via the mobile phone network. I saw it at a show recently. It looked like it would work with the NITs. I can't remember if it connected via bluetooth or if it was USB. It was quite expensive, but then all data access via mobile phone networks is very expensive in Canada.

EDIT: Their web page has a few USB modules; those would all probably require extra power and I wouldn't be surprised if special software was needed too... Sigh.
