iPhone SDK Key Leaked?

Mysterious folks in the iPhone hacking scene are claiming to have snagged the key for Apple's yet-to-be-released software development kit, a major feat if true. Says iPhone developer "Zibri:"

Since all iPhone applications must be properly signed for iTunes to process them and for the iPhone to load them, this key suggests that hackers are closer to creating compliant IPA application bundles for home-brew iTunes distribution. With the proper key, developers can create and distribute applications that load through iTunes without Apple's blessing.
