Hooray! This was strange though:

[root@ehoffman yum.repos.d]# yum install libmobiledevice
Loaded plugins: refresh-packagekit
Setting up Install Process
No package libmobiledevice available.
Nothing to do

[root@ehoffman yum.repos.d]# yum install libiphone libiphone-devel ifuse
Loaded plugins: refresh-packagekit
Setting up Install Process
Package libiphone is obsoleted by libimobiledevice, trying to install
libimobiledevice-1.0.1-1.fc12.i686 instead

Edit: I see it now - it’s libimobiledevice.
