Before people start dissing me for discriminating against users of different operating systems, such as providing ample amounts of information to Windows, few information for Mac users, and virtually no information for Linux users, here's a post dedicated to Linux users.

Since I'm not really a hardcore Linux user (although I do have it installed on one of my older computers), I'm not really in any position to provide advice or support. Nevertheless, the Linux community is a very supportive one, as seen in this guide to help P990i users set up their smart phone as a 3G modem. It also works for the P1i, so if you have both Linux and the P1i, why not take a look?
