Apple has released iOS 5 Beta 5 to the developers. While I am yet to personally try out the build, I am pretty sure this is just a bug fix release and nothing new has been added. You can download it from any of the links given at the bottom of this post.
Apple is getting close to the iOS 5 September release and the Beta 5 incorporates almost everything that we are about to get in the new mobile operating system. Right now, only developers can download but we found its IPSW files on other sites and thus we are sharing them for download with the non developers.
