Air Mobs creates a local mobile community to allow users to freely share Internet access among diverse carrier 3G and 4G data accounts. We have built an app where anyone can advertise that they have bits and battery to spare and are willing to let other Air Mob members tether to them. They might do this if they are near their data cap and either need a little more data, or have some they are willing to let others use before it expires. A website tracks the evolution of the community and posts the biggest donators and users of the system. To date, this app works on Android devices. It is designed to be open and community-based. We may experiment with market credits for sharing airtime and adding other devices and features.
