I was up in northern Iowa on a case and brought my Air with me and had my iPhone; there was no Edge or 3G network present, nor any WiFi. I had downloaded materials to the iPhone [doing the file
sharing thing while the iPhone was connected in the office] and they were in AirSharing & Files, but not on the computer where I needed/wanted them. I needed to move them from the iPhone to the Air.
For some wierd reason, perhaps unimportant to me now, I couldn't get Bluetooth to work. Air could see iPhone and they paired but they couldn't communicate. That task is for another day.
But I then went to the Air's airport and created a Network. I forget the precise steps next but I was then able to open the iPhone's directories of both the AirSharing and Files items in Safari and download the desired files from the iPhone to the Air, over the network I had created. I have to admit to thinking it was pretty neat, even if more experienced hands say HO HUM. [pic is of modern Iowa farm, windmills and all]
