Pete let me know that Foursquare has updated their BlackBerry application to version 1.9.5 with a few much needed features and improvements. This release adds push notifications and lazy loading of user/venue pages for faster loading. Here are the highlights:

• Push Notification – Now receive check-in notifications instantly via BlackBerry’s push notification service!
• Faster User and Venue Screens - Now foursquare loads user and venue data as it gets downloaded, allowing you to view a user profile instantly without having to wait for all the data at once.
• Improved Battery Life – With true push notifications enabled and a few additional tweaks, battery life continues to improve.
• UI Improvements for Touch – Additionally we’ve focused on the experience for BlackBerry touch users. Improving the menu system and making small changes throughout the application

The Foursquare app is available for most Blackberry smartphones. For more info go to foursquare.com/blackberry or to download the app OTA click here from your BlackBerry browser. Also, if you’re attending BlackBerry DEVCON 2010, don’t forget to check-in with the app for a badge and prizes!
