We mentioned Aloqa a bit back when it was in beta but it was limited to the Curve 8900 and Bold 9000. Now the app is out of Beta and is available for a broader range of devices including the Tour, 83XX series, 88XX series, 87XX series, and 8520. The app is now also feeding you information in the US, Canada, & Austria.
Aloqa supposedly lets you find interesting places, events, & friends near you. I am not sure exactly how it pulls that off but supposedly they are fed information from Facebook Connect, Yelp, Eventful, last.fm, Wikipedia, Craigslist, Topix, Fon, Coulomb Technologies, GreatDad, Google Maps API, Qype, Call-A-Bike, Nestoria, and BeLocal.
It looks like a pretty interesting app if you want to give it a spin and the price is right (free). Check it out at www.aloqa.com and let me know what you find!
