Hello,
The first version of my FourSquare client is in the extras-devel repository.
You can use this install file for easy install.

It is far from feature complete. At this moment you can checkin, and see where your friends are. More features will be implemented over time.

Donations are welcome, since I have already put an huge amount of time in it, and donations will motivate me for more updates (=features).
