How would you like to use your laptop computer even when there’s no WiFi connection. Well you can, just as long as you have the Droid, decent cell connection, and the PdaNet app.
PdaNet is just a regular Android app with super magical powers that “tethers” the Android phone to your laptop allowing you to use your data connection from your phone to get online.
