The Security Mentor

There's a Pocket-sized tool that will scan for and join Wi-Fi networks, crack their security if possible, read any shared folders from computers on the network, and launch attacks against them from a library of attack techniques.

The only thing new here is that it's small and doesn't require technical knowledge. People have been doing the same thing with laptops and free software for years.

The target market is government. So this doesn't affect you unless you're doing something illegal, like downloading music, or something suspected of being terrorist, like protesting the war.

There's no change to how you need to secure your wireless network. Ignore anything called "WEP" in the configuration screens, use strong passwords if you use "WPA", and since secure setup is such a pain with today's gear consider scrapping everything and buying new gadgets that support "WPS", a setup standard that's supposed to make the process feasible for people who have other things to do.
