The temporariness must be the reason iPhone Dev released the iPod Touch 2G jailbreak solution silently. Anyways, people seeking desperately to jailbreak the player can head over to RedSn0w to download Redsn0w Lite. The ‘Lite’ tag along with Redsn0w denotes it as a tethered jailbreak, meaning you need to run the jailbreak commands each time you restart the device.
The tool is for Mac only and the team does not offer any support for the release. In short, use it at your own risk.
