Comment 6 for bug 803149

I am working on this but I was unaware of this particular bug report until yesterday.

Foursquare's changes seem to be two fold. Firstly, they're moving everything to use oauth and getting rid of the password method of authenticating. Secondly, they're moving from API version 1 to version 2.

I've been struggling to figure out how their implementation of oauth works for what feels like 6 months. Fortunately, in the past couple of days, I've had a breakthrough. At this point, I can authenticate with foursquare, so part 1 is done, but I have not yet transitioned the api parts from version 1 to version 2. Hopefully, if I get time in the next day or so, that should be done too, at which point, I'll attach a branch for consideration.
