iPod or iPhone won't mount in Linux? libimobildevice!

Problem: "lock (-5)" or unable to mount errors trying to load iPod.

Solution: I was runnung OS 4.2.1.
In November that support was added:

27.11.2010: libimobiledevice 1.0.4 has been released. One important change is a fix to connect to iOS 4.2.1 devices.

Standard packages are using 1.01.

Find new packages for
openSUSE 11.0, 11.1, 11.2, Factory or 1-Click Install
Fedora 12+ (Packages in the official repositories)
Mandriva (Packages are available in "Cooker")
Ubuntu (Karmic, Lucid)
Debian
or the source file at:

Ipod Touch Lockdown Error (-5) on Linux Mint Debian

I was getting a lockdown (-5) error every time I tried to connect my iPod to my Linux Mint Debian Edition.

PARTLY FIXED:
The answer was apparently somewhere in the addition of this Ubuntu PPA. I had most, but not all of the packages.

I ran the instructions, then ran a regular mint updated, and suddenly my iPod was recognized. Sort of. I can drag and drop music in and out of my iPod, but not play, or even be recognized through Banshee, Rhythmbox or GTKPod.
