4) Connect the iPhone. Hit Cancel if you are asked if you wish to open it as a camera to import pictures.
After connecting the IPhone i got a "Unable to mount leo's IPhone - Unhandled Lockdown error (-4)". It's actually a known problem and is related to the package libimobiledevice1. As i'm running a mixed squeeze/sid system, i also installed the sid package libimobiledevice2 but it didn't seem to change anything.
