To tether a Windows Mobile 6 cell phone (make sure you have a data plan that allows tethering), you will need to install a few things:
sudo aptitude install subversion build-essential linux-headers-`uname -r`
Once those are installed, we need to download and build the latest usb-rndis-lite code:
svn co http://synce.svn.sourceforge.net/svnroot/synce/trunk/usb-rndis-lite
cd usb-rndis-lite/
make
## remove the existing usb-rndis drivers with clean.sh
sudo ./clean.sh
sudo make install
Before you plug in the cell phone, you will need to blacklist the rndis_wlan kernel module:
sudo echo "blacklist rndis_wlan" >> /etc/modprobe.d/blacklist
sudo rmmod rndis_wlan
Plug in your cell phone. If you type “dmesg”, you will see something like the following:
[ 152.312099] usb 4-1: new full speed USB device using uhci_hcd and address 3
[ 152.500604] usb 4-1: configuration #1 chosen from 1 choice
[ 154.138352] rndis0: register ‘rndis_host’ at usb-0000:00:1d.3-1, RNDIS device (SynCE patched), 80:00:60:0f:e8:00
[ 164.441074] rndis0: no IPv6 routers present
This is showing that the phone was found. Let’s take a look at the list of interfaces using ifconfig:
….
rndis0 Link encap:Ethernet HWaddr 80:00:60:0f:e8:00
inet addr:169.254.2.2 Bcast:169.254.2.255 Mask:255.255.255.0

RX bytes:2097 (2.0 KB) TX bytes:9146 (9.1 KB)
On the phone, turn on Internet Connection Sharing and connect via USB. Wait a few seconds (obtaining an ip address can take up to a minute or so) then issue the ifconfig command again:
….

Yay! We are connected.
In order to use Firefox, Pidgin or any other software that uses Network Manager, you need to stop the Network Manager daemon:
sudo /etc/init.d/NetworkManager stop
You will be able to use your applications again
