I already provided the Norwegian link for unlocking an iPhone locked by Netcom (also, you can unlock it at any time, but if your contract hasn't run out there's a penalty fee, based on the reminder of your contract).
Here is the press release from Netcom about enabeling Visual Voicemail July 6th:

Here is the one with the iPhone 3GS plans and prices, which also announces tethering for any iPhone with OS 3 with Netcom as carrier:

Use google translate or something if you cannot read Norwegian.
And if you google Netcom and tethering you'll find a lot of blog posts around the time it was actually activated, ~August 3rd, a couple of days after the 3GS was released in Norway.
Also, if you gonna pick a fight, please do it about something you have any knowledge at all about, with someone who cannot have you banned for trolling...
