I think this is our first ever hack, heavily copied from here (thanks to that author) with a few little changes for the UK T-mobile network, and shows how to use a nokia e90 mobile phone over bluetooth as a 3G modem on T-mobile on ubuntu 8.10, saving yoruself the cost of buying a £150 USB 3G dongle

First Pair your Mobile to Your laptop Manually…using bluetooth manager.. if pc is not connecting to your device.. try to connect the pc from your mobile

then go to console n issue the following command

adrian@adrian-laptop:~$ sdptool search DUN

paste the text in it

rfcomm0 {

save it

step 4:

sudo gedit /etc/ppp/peers/airtel

copy this in that file

/dev/rfcomm0 115200
connect ‘/usr/sbin/chat -v -f /etc/ppp/chat-gprs’
crtscts
modem -detach
noccp
defaultroute
usepeerdns
noauth
ipcp-accept-remote
ipcp-accept-local
noipdefault

step 5:

issue the command

sudo gedit /etc/ppp/chat-gprs

copy this in the file

” ATZ OK
AT+CGDCONT=1,”IP”,”general.t-mobile.uk”
OK “ATD*99***1#”
CONNECT ”
step 6:

FINISHED

To run it,make sure you are not connected to another wifi network (reboot in needed), then  just issue this command

sudo pppd call airtel

It works, and has just saved me £150 for a 3G wireless USB dongle device.
