I have Tetherme running, and I've put a really hard password on it with letters and numbers that you really couldn't guess unless you read my mind. I only have one wifi-capable device other than my iPhone: my Mac. Yet tetherme says I have 2 connections. . . . My iPad is in my car, downstairs and in the parking lot. Can the wifi signal really reach that far? Or is my iPhone counting itself for some reason?
