Location based social network Loopt has recently updated their BlackBerry client to include LooptPulse which brings Foursquare like check-in capability that allows you to leave tips and share information with others. LooptPulse also generates recommendations on locations using data from its partners like Zagat, CitySearch, Bing, and Tastingtable (recently added partners include SonicLiving, Zvents, and Metromix).
Loopt for BlackBerry
There is a new version of Loopt for the BlackBerry out with some pretty cool new features… My favorite being the ability to launch Loopt directly from your contacts. The map is also its own tab now, making it easier to locate your friends.
