Foursquare posted on its blog today that the popular check-in service would be available on the phones using the Nokia S40 operating system. The Nokia Beta Labs team have built it using the Foursquare API.

It’s a full-featured Foursquare app. Including all the well know features such as; check-ins, shouts, venue discovery and friend info. The Nokia Beta Labs team are still developing the product so there will be more additions and changes coming soon.

If you have a S40 device such as the Nokia 5310, 6600 fold, 7230, C3-00, C3-01, and X3-02, you can download the beta now.

With Nokia replacing its Symbian OS with Microsoft’s Windows Phone 7, it’s interesting to see the Nokia team still pushing forward with development of new apps. Nokia’s transition to Windows Phone 7 will reportedly take place within two months.

Watch the short video below to see the app in action on a Nokia handset:
