A lot of you people are asking questions that you can answer yourself. It's probably already answered in this description, or on Google. Relying on YouTube videos won't help you learn anything. Experimentation is always great.

" Jailbreak iPhone OS 4.0 Beta 1 and 4 with redsn0w 0.9.5 beta 2 : http://bit.ly/adfB7e
* iPhone OS 4.0 UDID Activation: http://bit.ly/almlDc
Sorry about the poor video quality. Made the bitrate rather low so it would render and upload quickly. Quality turned out okay though :).
redsn0w 0.9.5 beta 2 was just released, which jailbreaks iPhone OS 4.0 beta 1 running on the iPhone 3G (that's currently the only device that can be jailbroken). It also only works on Mac OS X, and it doesn't hacktivate the firmware (your UDID still needs to be registered to install the firmware, see here http://bit.ly/almlDc for details).
Please visit the first link above for updates on iPhone OS 4.0 (http://bit.ly/adfB7e) for updates regarding the jailbreak, and about what is working and what isn't working.
