how to use the wireless modem huawei e220 on ubuntu?

Hi, i got ubuntu 8.04 version and was trying to use my huawei wireless usb modem. But when i plug it in my laptop it doesnt appear in my computer.
I have been reading some articles about it and i think the problem was with the old kernels or something.
well i dont really know how to make it work on ubuntu.
Im guessing ill need some kind of program to detect the modem and dial it for me? and i wont be able to use the default on?

The modem in windows is detected as a cd-drive and it got the software on it to be able to connect to the internet and send sms etc.
But it just seems its not being detected on ubuntu.

For kernels later than - hmm, I can't rememeber if it's 2.6.16 or 2.6.18 - all you need to do is load the 'options' driver. In fact, I would expect it to be loaded when you plug in the gizmo.

If the driver is running, you will have a /dev/ttyUSB0 and /dev/ttyUSB1.
You can just use 'pppconfig' to configure to use the modem; with the 'option' driver the serial speed you specify is ignored. For the "username" you can put in anything; same with the "password". The dial command on the other hand is "ATD*99***1#" for dialing local AND roaming. I forget the number to dial for local only - not that it matters unless you go to another country.

Since the 3G/GPRS signal often drops out, you may wish to make the pppd connection "persistent" and "on demand". If asked, you also want to usepeerdns and usepeerdefaultroute.

I have had a few problems with the E220 modem though - I suspect there may be a few revisions. My modem always just ran, but I borrowed a modem from a friend once and getting it to work was annoying - the usbstorage drivers were loading and fouling things. To get it to run I had to:
rmmod option
rmmod usbserial
rmmod usb_storage
modprobe option
