The prospect of spotty little geeks roaming around with their PDAs snooping for private W-LAN hotspots hardly fills me with dread.
But, IO540, people who describe how to invade the privacy of others should consider their actions carefully. Yes, there is software designed by geeks to break into the legitimate W-LANs of others, but please don't make it easier for the little swine to do so.
If Plod had caught you driving around snooping as you were, I wonder what would have happened. "Going equipped to commit a crime" springs to mind.....
