+I was on the train today, needed some of the [Boost][0] manuals, and had
+no internet connection. So I wanted to use my phone (an old HTC Prophet
+with Windows Mobile 6.1) as a network access point to browse over
+GPRS/EDGE. As I found out, it is fairly simple with [Blueman][1] and it
+even provides [NetworkManager][2] integration, so all
+NetworkManager-capable applications can be notified about the
+connectivity.  Windows Mobile 6.1 allows tethering over a Bluetooth PAN
+([Personal Area Network][3]); but there is another method called DUN
+([Dial Up Networking][4]), which I will not describe here. So here is a
+step-by-step tutorial what I did for my PAN approach, with a few
+(german) screenshots, tested on Ubuntu 10.04 Lucid:
+
+* Since my laptop was running on Ubuntu Lucid, there was already a
+  recent Blueman version in the Ubuntu repos available. On older
+  systems, you may want to add the [Blueman Launchpad PPA][5].
+
+      $ sudo apt-add-repository ppa:blueman/ppa  # only necessary on pre-lucid systems
+      $ sudo aptitude update
+      $ sudo aptitude install blueman
+
+* Note that this also removes possibly installed `gnome-bluetooth`
+  packages since Blueman is an adequate replacement for the GNOME
+  Bluetooth UI.
+
+* After the installation has finished, I had to enable the NMPANSupport
+  plugin for NetworkManager 0.8 by right-clicking on the Blueman icon in
+  the GNOME notification area and selecting “Plugins”. For older
+  NetworkManager versions, there is also a plugin for NetworkManager
+  0.7, called NMIntegration.
+
+  <div class="gallery">

+  [[!img blueman-plugins.png alt="Blueman plugin page"]]
+  </div>
+
+* Then I activated tethering on my phone (“Programs” → “Internet
+  Sharing” on my Windows Mobile 6.1, but YMMV). Apparently this was
+  neccesary with my model, because without tethering enabled I could not
+  get a Bluetooth PAN connection in the next step.
+
+  <div class="gallery">
+  [[!img winmo-program-menu.png alt="Windows Mobile Program screen"]]
+  [[!img winmo-connection-sharing.png alt="Windows Mobile Internet
+         Sharing application"]]
+  </div >
+
+* I paired the phone and my laptop via Bluetooth, and created a PAN
+  (Personal Area Network) by connecting to the “Network Access Point”
+  service on the phone. In Blueman, all you have to do after pairing is
+  right-click on the device and select “Connect To: Network Access
+  Point”. This creates a new network device `bnep0` which is
+  automagically configured through NetworkManager (using [stateless
+  address autoconfiguration][6]).
+
+  <div class="gallery">
+  [[!img blueman-pan.png size=x100 alt="Blueman: Context menu for device
+      “Leia”, menu entry “Network Access Point” is selected"]]
+  </div>
+
+  (Yes, my phone is called [Leia][7]… I also have a yet another HTC
+  Prophet for testing purposes, which is called [Luke][8] :-))
+
+* However, in my setup, though I was able to ping certain IP adresses on
+  the internet, DNS lookups timed out for some reason. It got better
+  when I explicitly set an IP address for the Bluetooth PAN driver on my
+  phone, and did the tethering process all over again.
+
+  <div class="gallery">
+  [[!img winmo-connections.png alt="Windows Mobile System Settings
+      Screen, with item “Wi-Fi” selected"]]
+  [[!img winmo-networkdrivers.png alt="Windows Mobile Network Driver
+      settings screen, with menu item “Bluetooth PAN Driver” selected"]]
+  [[!img winmo-bluetooth-ip.png alt="Windows Mobile Bluetooth PAN Driver
+      settings screen"]]
+  </div>
+
+* And off I went with mobile internet access. Woo-hoo! \o/
+
+I may also add that the NetUsage plugin in Blueman is very reasonable to
+use ;-) After activated, the network usage can be viewed by
+right-clicking on the Blueman icon and selecting “Network Usage”.
