redsn0w, the long awaited iPod Touch 2G jailbreak, was announced a couple weeks ago, and released Saturday. The Dev Team folks bill it as "a no frills tethered jailbreak for iPod Touch 2G." The tool is a 16kb download here or here.

They also warn they will be providing no support whatsoever for this program, and will go so far as to ban your user ID from their blog if you post comments asking for support - its a slightly more complex process, and they don't want folks using it who don't know what they're doing. And I'm sure it makes perfect sense that as busy as these guys are, they don't have time to walk folks individually through the process the hundreds of thousands of times that will naturally wind up happening.

iPod Touch 2g 2.2.1 Firmware Download
They've laid out basic instructions on the site. We'll be writing up a full guide with screenshots, etc, sometime today or tomorrow. Until then, check out their README, and here's the gist:
-------------------------------------------------------------------
Basic instructions
-------------------------------------------------------------------
Note: these are the bare bones instructions. Please don't come to us
looking for more detailed instructions.
Preparation
1) Copy the FirmwareBundles and CustomPackages directories into
your PwnageTool.app/Contents/Resources directory
2) Create a custom 2.2.1 ipsw with PwnageTool in Advanced mode. Don't
enable custom boot logos.
3) From your custom 2.2.1 ipsw, extract these (patched) files:
iBSS.n72ap.RELEASE.dfu (name it iBSS221pwn.dfu)
iBoot.n72ap.RELEASE.img3 (name it iBoot221pwn.img3)
4) From the official 2.1.1 ipsw, extract this (unpatched) file:
iBSS.n72ap.RELEASE.dfu (name it iBSS211.dfu)
Installing the jailbroken custom ipsw
5) Put your ipt2g into DFU mode using keypresses. Don't have iTunes running!
6) Start rslite. Send the official iBSS from 2.1.1: !iBSS211.dfu
7) Start rslite again. Send the redsn0w-lite patch: #pwn211ibss.txt
8) Send the patched iBSS from 2.2.1: !iBSS221pwn.dfu
9) Use iTunes to do a full restore using your custom 2.2.1 ipsw
Tethered boot
After the install, your ipt2g will not be bootable without assistance
from a tethered computer. The method in this README.txt requires you
to go into DFU mode, but you should be able to find (or work out on
your own) other more convenient ways.
10) Repeat steps 5-8
11) Send the patched iBoot from 2.2.1: !iBoot221pwn.img3
Your homescreen should soon show up. You can then start iTunes.
