Prototype as in the early engineering test unit we saw briefly on Ebay and YouTube, we're guessing. Apple had that pulled. Will they be able to pull the firmware now that it's been leaked onto the internet? Probably not, but they'll likely not be able to pull Steve Jobs and his iCommandos off the person who leaked it either...

If it's not a gag, hoax, or other form for silly fun, getting a look at the origins of the iPhone OS could potentially help some developers... and some competitors.
