Free public Wi-Fi is incredibly convenient, but security can be an issue. Here's how to minimize the risk, whether you use a laptop, smartphone, or tablet.
The SecureKiss virtual private network service is relatively simple to install and use. The free version lets you transmit up to 300MB per day without having to register.
