How to connect to the internet using T-Mobile and bluetooth

I have a laptop with Debian, cell phone (Nokia N70) with bluetooth and this howto describes how to connect to the internet.

Connect USB bluetooth dongle to the laptop and check it:

$ hciconfig
hci0:   Type: USB
    BD Address: 00:02:72:D2:23:12 ACL MTU: 310:10 SCO MTU: 64:8
    UP RUNNING PSCAN ISCAN
    RX bytes:686 acl:0 sco:0 events:22 errors:0
    TX bytes:337 acl:0 sco:0 commands:21 errors:0

Scan for the phone:

$ hcitool scan
Scanning ...
    00:19:79:86:EB:BC       Nokia N70

Create a serial device for communicating with the modem in the phone:

$ rfcomm connect /dev/rfcomm0 00:19:79:86:EB:BC 3
Connected /dev/rfcomm0 to 00:19:79:86:EB:BC on channel 3
Press CTRL-C for hangup

(A dialog will popup on the phone asking me to allow the laptop to connect.)

Connect using wvdial:

$ wvdial
--> WvDial: Internet dialer version 1.56
--> Cannot get information for serial port.
--> Initializing modem.

ATZ

--> secondary DNS address 213.162.65.1
--> pppd: �[08][06][08]�[10][06][08]

And that's it, I am connected.
