BackTrack Mobile Beta Release: July 2010
Featuring packet injection, Karmetasploit, Social Engineering Toolkit .. oh my!
We are proud to announce that we are finally approaching a beta release of the first BackTrack Mobile operating system for the Nokia N900! The release will be public shortly before the Blackhat and Defcon conferences in July 2010.

We will provide a list of features and download instructions on our site and to those that have subscribed to the email update list once the beta is completed.

You can expect fully supported packet injection using the internal wl12xx (wl1251) driver with this release. And to reiterate our intentions, this project will be 100% free to download!
