Bluetooth Tethering your Ubuntu Jaunty netbook to iPhone running 3.0

Having access to an iPhone running the latest firmware, I was anxious
to get my netbook running Ubuntu 9.04 (Jaunty Jackalope).

It's easy once you install blueman from Synaptic package manager. For
whatever reason, the default Gnome bluetooth manager won't get the job
done.

Open up Bluetooth Manager from "System Preferences". Set your iPhone's
bluetooth to be discoverable.
The iPhone will show up in the list (if not, hit the 'Search' button).
Once it does, click on 'Bond'. 'Bond' will cause your iPhone to tell
you your netbook is trying to pair with it (It actually says 'Netbook
would like to pair with your iPhone', charmingly anthropomorphic).
You want that, so click 'Pair'.
Your iPhone will tell you to confirm that the same passkey is being
displayed in Blueman on your netbook. Confirm this on your netbook
too.
Once this is done, right click on the iPhone in Blueman. Under
'Network access', select 'Network access point'.
That's it, you're tethered. Your connection will show up in Network
Manager as 'bnep0'.

Netbook kernel redux (Virtualbox)

Right after you upgrade your kernel, Virtualbox is going to complain
that it can't load its corresponding kernel module.
Make sure you *also* install the corresponding Linux kernel headers
package and then reinstall Virtualbox.

Netbook kernel

This might seem a bit obvious, but until I installed the updates on
the husbinator's EeePC, I didn't know a netbook specific version of
the Linux kernel was available.
To get it on to your netbook, follow this link - http://array.org/ubuntu/setup.html

I installed it on the Lenovo S10. Haven't seen a *massive* jump in
performance like the Dothan-based Eee, but its a bit snappier.
