Google Chrome OS and Cr-48 and 3G connectivity using Vodafone, O2, T-Mobile UK

Despite rather lengthy title, the post itself will be rather short and straight to the point. If you are lucky owner of Cr-48 Chrome OS netbook and very inconsiderably live outside of the United States (like, you know, some of us happen to be), you can still get a joy of wireless 3G connectivity. Not without some caveats, though.

  1. To start with you will need to switch your Cr-48 to dev mode - which is easy if you follow this manual.

  2. While you're here, with your battery out, you can also plug in your SIM card into the laptop. Here's an information I figured by trial-and-error method: on current build, which is, Vodafone and O2 do not work. Of all SIM cards I had available, T-Mobile works with no problems whatsoever.

  3. Plug your battery back in, turn laptop on, wait a couple of seconds, login...

  4. Now press Ctrl-Alt-T. It will bring you to shell window. Since you're now in dev mode, you can type "shell" and get a real Linux console.

  5. Type "modem_set_carrier Generic UMTS" - no quotes, register matters. Press Enter. Wait to see command produce some output, which could make sense to some of us after all.

That's it. Now wait couple of minutes, and your laptop should see network called "Generic UMTS" when you click wireless connectivity sign. Do not do activation as it won't work anyway - just choose "Generic UMTS" in network list after clicking wireless icon, and with some luck soon it should connect. You can verify results by going into Network Settings, finding "Generic UMTS" connection and clicking Options button.

That's it boys and girls. Tell me if something doesn't work out, but don't hold your breath - I'm only wandering around, and sometimes discover something by accident :-)
