The recently-engaged street artist Posterchild has an idea for the city's payphone network. He declares since the payphones have basically become nothing more than an "adverting-revenue generating platform, then they should make all local calls free."

Tourists could avoid roaming charges, non-cell phone users (what?) could get in touch with people via telephone, and when your iPhone battery dies you could still make your call right there on the street. He calls his idea "FreePhone" and says that there would even be user-friendly dialing options. For instance, dialing "cab" would get you a taxi, dialing "info" would connect you to a tourism help desk, etc.

But maybe they should be free WiFi stations? What would you do with the city's payphones... or are they doomed to become extinct like the booths before them?
