It’s taken longer than I expected, but the beta firmware has been leaked, according to iClarfied. The article links to a post on Hackint0sh claiming the release to be real, though with today’s date, I’m taking everything with a pinch of salt!

The firmware is useless at the moment however, unless you have a valid developer authorisation, or access to the upcoming iPhone dev team too, pwnage.

First to post with this running wins a biscuit !
