While Yelp on the iPad has allowed reviews for quite some time, iPhone users were previously limited to adding short tips or drafting reviews that could be saved and added later via the website.
The new version of Yelp supports full reviews, and the former "Tip" button has now been replaced with a "Review" button that offers a standard review interface.
What's newYelp is a universal app that can be downloaded from the App Store for free. [Direct Link]
