I’ve started using Cloak VPN for my various iOS devices and laptops. It’s pretty cool so far…incredibly easy to set up and, well, it just works (and is free for a limited use account). I’ll report back once I’ve had a chance to test it out on various other wifi networks. If you’re not sure why a VPN matters, well, you better watch this video. While it highlights just one particular piece of software, there are many ways that other users of the same wireless network can eavesdrop on your network activity. With easy VPN solutions out there, there’s really no reason not to do this!
