Geohot, breaks from his long silence with merely a blog posting. He talks mainly about the jailbreak of the iPhone 4. He has successfully jailbreak his iPhone 4, but seems to have no plans to bring limera1n. As more people ask for a release date, the less Geohot seems to want to release a jailbreak tool.
George says when the time is appropriate and tool is ready he will made the tool available in public. In the meantime, you should keep your eye on a new program by Comex Jailbreak for all devices with the same rapidity of the iPad, iPhone Spirit Jailbreak.
Also a iPad, iPhone Flash or Frash hack is also available.

The real reason behind no release isn't technical. It's just that it will never stop, after blackra1n, people demand unlock, after blacksn0w, people demand untethered. I miss the days when jailbreaking and unlocking were difficult, it attracted a much higher caliber crowd.
