The site a Connectify.me continues to offer free software that allows you to use your Windows 7 notebook/desktop as a Virtual Wi-Fi Access Point, complete with WPA2 security. I have used it several times in the last weeks to help colleagues how are not fortunate enough to have Mobile Broadband cards. An interesting note: The Connectify blog reminds us that if you want to use your iPhone/Touch apps with Connectify, you need to remember to pre-load Bonjour for Windows on your notebooks, as many of the apps require that functionality to operate. Heads up!
