As he explains:
As far as a release goes, it probably won’t happen from me. limera1n is little more than a raindrop on a website; it was never mentioned by me previous to this post. pwned4life is a complete invention of some blogger in a basement somewhere. When I said pwned for life, I was referring to the original iPhone, 3G, and Touch; which of course are, by the aptly named PwnageTool.
He goes on to say to stay away from asking him about a release, for it just makes him want to release it later.
