== 1. Pairing your Laptop with your Cell Phone ==

First of all, you need to pair your laptop with your cell phone. You need an active internet connection to your laptop in order to download some packages. We will use the ''kdebluetooth'' package. Though I myself am a Gnome user, I have found this package very useful. So that let us open a console and type as root:
{{{
# apt-get install kdebluetooth
}}}
This will install the package. After that, just let us type as a normal user:
{{{
$ kbluetooth
}}}
Then a little blue icon will appear on the taskbar...

If we click on it with the right button of the mouse and choose the option CONFIGURE... ADAPTERS... then we will be able to configure the laptop in order to set it in DISCOVERABLE mode...

After this, we activate the Bluetooth '''on the cell phone''' and try '''to detect the laptop'''... Once discovered the laptop on the phone, it will prompt us to enter a numeric password: just type something easy like "123" in case you think there is no security threat... (It is just a one-time password). You will be prompted to repeat the same password '''on your laptop'''. To avoid repeating this process each time you pair your laptop with your cell phone, I highly recommend to add the laptop as a trusted device (this is an option easily accessible in the bluetooth menu '''on the cell phone''')... ''Et voi-là''... our devices are just paired!


== 2. Configuring MODEM Parameters ==

Now we need to configure the modem parameters of your cell phone. First connect the cell phone to the laptop computer with the USB cable... And then type as root:
{{{
# apt-get install wvdial
# wvdialconf
}}}
After doing this, ''wvdialconf'' has examined your cell phone and after a successful connection with it has determined the correct parameters of your modem and written it to a file. But now we must ''tweak'' this configuration file, so that we type as root:
{{{
# apt-get install gedit
# gedit /etc/wvdial.conf
}}}
You need to '''delete''' the following lines of code:
{{{
Modem Type = USB Modem
Modem = /dev/ttyACM0
}}}
And you need to '''add''' the following lines '''to the end''' of the file we are editing '''in the same order''' as it appears here:
{{{
New PPPD = yes
Phone = *99***1#
Username = MOVISTAR
Password = MOVISTAR
Init6= AT+CGDCONT=1,"IP","movistar.es"

[Dialer usb-scb]
Modem Type = USB Modem
Modem = /dev/ttyACM0

[Dialer blz-scb]
Modem = /dev/rfcomm0
}}}
Now we save the file without changing name nor location and we are ready. The cell phone modem is completely configured, and we can use it '''indistinctly''' via USB or Bluetooth (as you prefer) without changing any parameter...

== 3. Bringing Down the Network ==

Before connecting your laptop to your cell phone, we first need to bring down your existing network connection. To do that, we type as root:
{{{
# ifconfig eth0 down
# mv /etc/resolv.conf /etc/resolv.conf.eth0
# echo "nameserver 194.179.1.100" > /etc/resolv.conf
# echo "nameserver 194.179.1.101" >> /etc/resolv.conf
}}}
Obviously, these nameservers are valid only if you are connecting to the Spanish mobile net Movistar... And ''eth0'' is the name of your active network interface. In case you are not sure about the name of your interface, just type as root:
{{{
# ifconfig
}}}
And then all actives interfaces will appear...

== 4.A. Connecting via USB ==

If you want to connect your laptop to the internet via USB to your cell phone. Just connect the cables and type as root:
{{{
# wvdial usb-scb&
}}}

You are done. You can surf the web, or check your e-mail... ;-)

== 4.B. Connecting via Bluetooth ==

If you want to connect your laptop to the internet via Bluetooth to your cell phone. Just activate bluetooth both in the laptop and the cell phone, and then type as root:
{{{
# hcitool scan
}}}
The following information will appear:
{{{
Scanning...
    00:11:22:33:44:55 NameDevice
}}}
This is the MAC address and the name assigned to your cell phone Bluetooth device. Now you type as root (using the same MAC address as above):
{{{
# rfcomm connect 0 00:11:22:33:44:55 2&
}}}
After the connection is established, you type as root:
{{{
# wvdial blz-scb&
}}}

You are done. You can surf the web, or check your e-mail... ;-)

Hope you like it.
