So you already know that you can turn your iPhone into a hotspot, but a PUBLIC one? that anyone can use?
Here is the idea.
Its an app that allows you to create a public hotspot that anyone can access with NO password. But for the user to access the hotspot, they need to watch a 10 second video advertisement.
Video ads pay anywhere form $30-80 CPM (cost per thousand impressions).
The app provider can organize rev share with its users, so that they get a percentage of the advertisement revenue (say 50/50).
This could be a great additional revenue stream for cab or bus drivers, or just a great way to offset your phone bill costs.
