I'm still trying to wrap my head around this new phone service, but from what I've learned, it sounds ingenious. Sonopia is a new mobile and web experience that allows people to build their own phone plans according to their interests and start selling them to others. You can also create a personal profile to share with friends online and on the phone.
The actual Sonopia service is run by Verizon and Vodaphone. Oddly enough, Sonopia takes care of all the grunt work- including passing out headsets, sending out monthly bills, and dealing with basic customer service. The person who creates the phone plan takes care of the customers and the revenue.
It's free, has fairly easy set up and doesn't require you to sign up to your own mobile service. As I said, interesting but, I'll have to do a bit more research on this one! What do you think?
