Download Aardvark Mobile iPhone App for Free, Uses Push Notifications

We just heard from the folks at Aardvark that they have launched their mobile iPhone app and its available for free on the App Store. Whats AardvarkÂ ? Its a cool IM based Social Search application where users share their expertise for free. You canÂ either Ask or Answer questions from your friends or other users. This used to work over Chat but now they have extended their offerings with a cool iPhone app which brings almost all the features of Aardvark to your iPhone / iPod. I just asked a question on my iPod about the N900 shipping date. The app says it will alert you via PUSH notification if it finds an answer. I quit the app and go back to the homescreen. Within 2 mins I get an notification that Sven has answered my question already.
