More and more retailers are using the iPhone to capture customer eyeballs outside of their shopping experience. Outdoor retailer The North Face is no exception, with the launch of their updated, Twitter-filled Snow Report 2.0 app today, giving skiers and snowboarders access to aggregated resort-specific Twitter updates, weather, and snow condition feeds.

While The North Face already had an iPhone Snow Report app, the new version adds the Twitter feeds, which they claim is the first to aggregate topical information and Twitter news feeds into one application. It also lets users Tweet their own updates directly from the application.

Of course, the app is designed to increase sales. It also includes a The North Face store locator. Meanwhile, specific ski resorts are on the iPhone app bandwagon to improve customer experience on and off the mountain. Jackson Hole recently developed an iPhone application, available early next month, that features their winter trail map with iPhone’s built-in GPS technology, locating the user by pinpointing his or her location on the ski resort’s trail map. Big Air Software, separately, is marketing its iTrailmap 3D, which pulls from a database of over 500 resort trail maps and records a snowboarder or skiers trails throughout the day.
