This is an unofficial announcement. The suspense was killing me. Keeping this a secret was like having a huge box of chocolates I'm not allowed to open.
As a result of the ruckus a few weeks back, Alex decided to push forward with a download guide for the Mobipocket format ebooks here on MobileRead. It needs some polishing, but this early version is very good.

P.S. The guide is updated daily, and there is a link inside so you can get the next version.
