iPhone 4 not detected

The version of libimobiledevice that comes with ubuntu is old, try upgrading.

sudo apt-get update
sudo apt-get upgrade

Ok thanks! I did an update/upgrade after having added the ppa:pmcenery/ppa (which I forgot before) and I upgraded all:

• ipheth-utils
• libimobiledevice1
• libusbmuxd1
• libusbmuxd1-dbg
• usbmuxd

So, nothing more now unfortunatly! I plug and it does not work! Please help me again!

try mounting it manually.

sudo usbmuxd &
mkdir ~/iPhone
ifuse ~/iPhone

You might have to install ifuse.

sudo apt-get install ifuse

Thanks a lot! I did what you said and everything is OK. I can navigate then in ~/iPhone and see all my stuffs. Am going to try all the programs for video, music, synch and so on.

Is there a particular way to unmount? Can I directly unplug my iPhone?

Another question, can I manually put my music in a folder of my iPhone with a copy/past (then which folder is it?) or should I do it via a program?

you can unmount it with
sudo umount ~/iPhone

you can use gtkpod to put music on it. rhythmbox might work too.

Thanks a lot for your help!
