The long awaited public beta release of Flash Builder 4 (formerly Flex Builder) and Flash Catalyst are now available for download from Adobe Labs site.

Just after hours of the release there were quite a lot of tutorials, how-to’s and reviews all over the web from Adobe’s Platform Evangelists and a few other prominent developers. 

Adobe has compiled a very useful set of videos which illustrate the various features in Flash Builder 4 and Flash Catalyst here.
