Intelligent Design Communications today introduces Yodel 1.0, their new personal safety network utility for iPhone 3G, iPhone 3GS, and iPhone 4. Yodel turns an iPhone into a safety beacon for people who enjoy outdoor sports and activities. A message is formatted with the user’s activity/route, estimated time of return and location coordinates and sent via SMS and/or email to selected contacts. Along the way, they can send waypoints or activate an S.O.S. emergency system, with one simple action.
