Yelp for iOS was updated to version 7.0.0 today, adding a much desired review feature. After installing the update, users will be able to add reviews to any business or restaurant from their phones. 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 new Today’s release is pretty epic, and we’re not kidding around. Are you sitting down? You might want to sit down. Starting today, you can add reviews from your phone! Visit any business page, tap "add review", and go ban
