Importing photos from an iPhone using CentOS 6.3

For some reason, plugging an iPhone to a computer running CentOS 6.3 wasn't allowing me to access the pictures I had on it or import them. In order to have it work and being able to browse the pictures, here is what I did:

1. Plugged the iPhone using the USB cable
2. Took the iPhone in my hands and unlocked it using the "slide to unlock"
3. Opened Nautilus and browsed the content of the iPhone

Not unlocking the iPhone would allow to mount the iPhone, browse the content but wouldn't display the pictures in the "DCIM" folder.
