Ubuntu Linux + Nokia 5800 XM = 3G Internet Connection

I'm pretty sure that this had already been done before, I am just putting it here so I will remember it later ;)

Okay...

Step 1.Make your bluetooth device discoverable (just for a few seconds, at least)

Step 2.run this command:

% hcitool scan

Find the line that looks like

C0:XX:XX:XX:XX:00 Renz phone

That previous command gives you the bdaddr (Bluetooth Device Address) of your phone. I placed Xs in there (just to secure the phone, yours would actually be HEX Digits.=)

Step 3.Find out your device's DUN (Dial Up Networking) channel by running:

% sdptool search DUN C0:XX:XX:XX:XX:00 

You may come up with the following:

Inquiring ...
Searching for DUN on C0:XX:XX:XX:XX:00 ...
Service Name: Dial-Up Networking
Service RecHandle: 0x10012
Service Class ID List:
  "Dialup Networking" (0x1103)
Protocol Descriptor List:
  "L2CAP" (0x0100)
  "RFCOMM" (0x0003)
    Channel: 22
Language Base Attr List:
  code_ISO639: 0x454e
  encoding:    0x6a
  base_offset: 0x100
Profile Descriptor List:
  "Dialup Networking" (0x1103)
    Version: 0x0100

From here, we can infer that our Dialup Networking Service is @ channel 22

Step 4.Bind your rfcomm0 to this channel:

% rfcomm bind 0 C0:XX:XX:XX:XX:00 22

We basically tell rfcomm to bind to rfcomm0 using our bdaddr(C0:XX:XX:XX:XX:00) to channel 22.

Step 5.Configure your wvdial by editing /etc/wvdial.conf and putting in:

[Dialer Defaults]
phone=*99#
Modem=/dev/rfcomm0
Username=putyourusernameanythingwilldo
Password=putanythingheresmartdoesnotcare
New PPPD=yes
Stupid Mode=yes
Init1=ATZ
Init2=ATQ0 V1 E1 S0=0 & C1 &D2+FCLASS=0
baud=460800

Step 6.Run wvdial:

% wvdial

Be careful not to press ctrl-c while wvdial is running or else, you will get disconnected.

That's it! Have fun!
