Transfer iPhone photos to Linux
The iPhone uses a proprietary library on Windows and Mac to transfer photos from the iPhone to the computer. Presumably, they’re doing this to prevent playing with the phone’s other contents (files).
Someone has written a replacement driver for Linux which allows access to the photos. It looks like he reverse-engineered the protocol. More details are at: iFuse main page. If you follow the directions and install ifuse, then when you attach your iPhone to your computer, you will see a new “iPhone” directory under /media (at least on kubuntu). You’ll find your pictures under there.
I used a first-generation 8GB iPhone with 2.x firmware. Your mileage may vary with other combinations.
