Expat shield (http://www.expatshield.com/) is the only VPN service I have found that is apparently free to use. I suppose they must use an advertising based business model to pay for it.
This would be great if the thing actually worked!
The installation went well enough. When you start the service, it opens your default browser with a button to connect… it didn’t! I uninstalled it and re-installed it, tried with the latest versions of four different browsers (Chrome, Firefox, IE and Opera) and even installed it on an XP machine. Not a sausage! Bit of a shame really as it would be nice to able to watch the BBC and Hula for free.
