Our sister site, Engadget, unveiled its iPhone app [iTunes link] today. The free app functions in the same way as the current TUAW app [iTunes link] by delivering a constant stream of news from the site. Engadget's app will cover news from the main site, Engadget Mobile and Engadget HD.
Among the app's features are sharing articles through Twitter, Facebook or e-mail, the ability to tip Engadget on breaking news, and the ability to bookmark and view articles offline. A full list of features can be found here.
