I was hoping that somebody that knows about the hardware limitations of the iPhone and what the software can do could answer this - Would it be possible using the new accessories support to use the iPhone to geotag photos on my SLR camera? I have a Canon 400D (though I'm sure people that have other cameras would be interested too) Either through a connection from the camera to the dock, or perhaps adding a reciever to the camera which can communicate to the phone through bluetooth? If you can do this with the diabetic device then hopefully this would be capable with a camera. It would be so useful as most people have thier phones on them at all times - so to have the camera connected constantly to the phone in your pocket would be great. Any ideas?
