Yelp's version 2.0 of its iPhone app has officially hit Apple's App store. We reported on Yelp's focus on the mobile space and its importance here.
As we wrote recently, the new app gives consumers even more ease in automatically reviewing businesses via their iPhone and enhances its exiting GPS capabilities. The updated version of the app now lets Yelpers write reviews directly from their iPhone through a Twitter-like ?Quick Tips? feature that allows users to create 140 character tips. This was sorely lacking in the original version. The tips will be accessible on the iPhone app and the site itself (if popular) and will also be shown in a feed using GPS capabilities when users search businesses.
