I just spotted this on mmorpg.com: All Points Bulletin: Closed Beta Instructions - News Discussion - General Discussion - MMORPG.com Forums Heres the link to the blog page APB-Reloaded: End of Week 8 Update : Steps to Join the Beta
those who registered there in b4 the 15th of feb by inputting you email, should have will will be getting an application email now or very soon. Good luck. the key that you get in the email is only for aplication not the actual beta!
I received a key as well - keep in mind that this is just the key for the beta application, actual beta invitations will be sent out after they've reviewed the applications.
