iPhone SDK key leaked?

We're not exactly sure how this all went down, but we trust Erica Sadun over at TUAW when she says that it appears that the iPhone's SDK key -- which will probably be required by all "official" third-party apps -- has been leaked. Two different sites currently have the key posted, but it's all just for show until next month, when the SDK hits for real -- and the code is undoubtedly changed.
