Borderlands - Early Copies Locked

Apparently some retailers have broken the street date on the PC version of Borderlands - but they can't be activated.  Here's what 2K's Community Manager had to say:

Yesterday we learned that a fraction of the PC copies of Borderlands were accidentally sold to consumers in some countries but that gamers could not activate their copies yet. Since we learned of this problem, we have been looking into the issue to find the best possible solution for everyone.

I'm going to be completely honest with you guys right now. It is not possible for us to move the planned release date of the game forward. We could not possibly get the games into stores worldwide and out for digital distribution any earlier than planned. Less than 1% of all copies were sold, and if we unlocked the game today, illegal versions would most likely appear on torrents by the evening. I am sure all of you want our PC launch to be as successful as possible, and we simply won't be able to manage that any earlier than already planned.

I want to apologize for those of you who have gotten the game ahead of our release date, and ask for your patience and understanding. The game will be ready in the US and Canada at midnight eastern standard time on Monday, October 26th, and internationally by Friday, October 30th.
