Simple explanation of the dangers of using public WiFi:
Use of WiFi service in cafes is popular in Buenos Aires, though I believe most cafes have encrypted networks. We have Fibertel in our apartment, and because it is not completely unusual for us to have periods of service interruptions, we have sometimes needed to flee our own dark spot for a cafe. It has occasionally crossed my mind that, though encrypted, these networks should be used judiciously. Are they safe to use?
This brings me back to the subject of VPN's. Witopia has been recommended to me for use in Latin American countries. Has anyone any thoughts on Witopia or other VPN's, subsequent to our earlier thread on this subject?
