The official Foursquare app for Windows Phone has been updated to version 2.9. With the new version, it includes Push Notification when friends checked in. One other improvement includes more language support.
Here are the change log.
- Portugese, Korean, Indonesian, Japanese and Russian language support
- Push notifications to get instant friend check-in updates on pinned tile
- Leaderboard pinned tile backside to see where you stand compared to your friends
Seriously, I still think 4th & Mayor did an awesome job. If you have tried both, you should see some differences. I love the fast response of 4th & Mayor. Seriously, Foursquare needs to have a better support for Windows Phone.
