If you use your iPad or iPhone in public, unsecured wifi networks, you might consider trying out the new Opera VPN browser. Read more here. I plan to give it a try since I use public wifi frequently, especially when we travel. The VPN service is provided by 'SurfEasy'. Website here.
The use of the Opera browser is very small, at only about 2% market share. This VPN service is their way to try and attract more users. It will be interesting to see, first, how well Opera VPN works and, second, how successful their strategy turns out to be.
