A free consumer-grade VPN service
TunnelBear is a rudimentary VPN service that can be used freely after registration, the free user receiving 500MB of bandwidth per month. If the user pays a monthly fee, they can go beyond that bandwidth cap.
The service offers connections from the UK, the US and perhaps more in the future, enabling users to access websites and content restricted to these countries by licensing rules.
The paid version is also available as an iPad/iPhone app.
The service does not provide verbose logs and offers a less sophisticated UI than Viscosity, and practically no configuration options of any kind.
