I shall explain - my college has no wireless, and i needed to email some work to myself to print out (as plugging in a computer to the network is banned) I created a wireless network on my MacBook, made my iPhone 3G connect to it. Nothing not a glimmer, after playing about with airsharing for 10 minutes and re-leasing the settings on the network (on my phone) i managed to make my phone tether itself to my computer. I was online, downloading e-mail and surfing the web ! I have no idea how i did it, or what happened. We tried it with my friends MBP but had no luck the same procedure would not work on a MBP but would on my MB. Odd, yes. Amazing, yes. But how did i actually do it ? Can it be redone ? Can it be exploited ?
