A heads-up for fellow duders: the access code for the final phase of the Dark Souls II beta has been publicly announced, and anyone with a PS3 can use it to get into the third and final phase of the beta (edit: code has been clarified to be valid only in "American territories"). I just used the code and got in, myself.
This code is universal and was posted publicly by Namco minutes ago on their official Facebook page, so it is meant to be used by anyone who wants it. However, it will expire after 90000 people have redeemed it, so don't wait too long.
You can redeem on the code on your PS3, by going to the PlayStation Store and selecting Redeem Code. Alternatively, you can redeem the code by signing into your SEN (PSN) account on the official website here:
The beta itself is not live for playing yet, but will be live for a brief 3 hour stretch, starting on October 27 from 2 AM to 5 AM EDT (A.K.A. Oct 26 11 PM to Oct 27 2 AM PDT). This means, if you successfully redeem the code above and download the game client on your PS3, you'll be able to start up the game and play only during that 3 hour window, not before or after then.
The content of this last phase of the beta is expected to be the same as that of the first two phases.
