Please refer to art Ubuntu 10.10 and iPhone tethering [SOLVED & UPDATED]
Last week, with the new Ubuntu 10.10 I had a lot of problem using my iPhone 3Gs (FW 4.1) with tethering. Simply I cannot use my iPhone to connect to the internet.
I've found two solutions:
The first one is the simplest, just update the kernel to version 2.6.35-22-generic #35, to do this action you need to launch the update manager and then install all the updates.
For those who don't want to update the kernel, follow these instruction:
Set repositories:
# sudo add-apt-repository ppa:pmcenery/ppa
# sudo apt-get update
Then install the drivers:
# sudo apt-get install gvfs ipheth-dkms ipheth-utils
Now, on an upgrade these are already installed, and even a re-installation failed:
# sudo apt-get install –reinstall gvfs ipheth-dkms ipheth-utils
For me this worked well
