I thought you had to be a member before a specific firmware was released to get that firmware?

On the iOS Dev Center, there are tabs for the iOS SDK 4.2 and iOS SDK beta.

The beta downloads contains the following description;

Xcode 4 Developer Preview 5

This is a pre-release version of Xcode 4, a major new release of Xcode for both Mac and iOS development. This release requires Mac OS X 10.6 Snow Leopard, and includes the iOS SDK 4.2 GM seed, to develop apps for Mac, iPhone, and iPad. Please review the Release Notes and Readme before installing this software.

The dev team have included links to the 4.2b3 ipsw files on the Apple Developer site as a part of their post about the latest release of redsn0w. Of course, you have to be a developer to login and get them.
