Using phone as portable wi-fi spot
Just dropped daughter off at uni and her network access wasn't working (I think she didn't pay enough attention when they passed out passwords :) ) so I rememberd that one of the features of Android 2.2 was that you can use your 'droid as a portable wi-fi hotspot generator :)
Switched it on and connected her laptop to it just like at home - easy peasy :)
And, I can use the the same technique at work to get around filtering issues in future :)
PS It made me think of how do you big boys and girls stop your darling high school pupils from doing the same thing?
