After a few days of internet troubles at work, I decided to attempt USB tethering with my Nokia N9 before Facebook withdrawal killed me (I'd browse on mobile but the only place I get signal is hanging off my desk which makes typing a bit awkward). This is a little more involved than on other platforms - if you have wifi you can use the included hotspot app, but I couldn't be bothered to walk the whole 15 minutes home to grab a wireless card. I knew that the SDK app you get when you enable developer mode (you have done this, right? Settings -> Security -> Developer Mode and hit the button) lets you set up a network over USB so you can SSH to the N9, and figured I could simply set up an SSH tunnel and proxy all my PC traffic through that. Course, it's never that easy.
