For the past few weeks users have been waiting patiently (or impatiently as the case may be) after news that the dev-team had managed to jailbreak the 2nd generation iPod touch, but there’s a catch: the device cannot be restarted without being connected to a desktop machine, restarting while out and about will result in a device that will not boot.

The dev-team had been waiting until they could get around Apples restrictions at a lower level, but stated on twitter and elsewhere that if they could not find a way to get into the device at a lower level, they would release a limited, tethered jailbreak for those who were willing to take the risk. So what exactly is the risk? We will let the dev teams note speak for itself, but for those willing to test the method out, the software and instructions required are on the bottom of the redsn0w website available here:

THIS IS A ***** TETHERED ***** JAILBREAK
IF YOU DON'T KNOW EXACTLY WHAT THAT MEANS, DON'T USE THIS!

There are many ways to do this. Here's one way that will probably
work for you. If it doesn't, please don't come to use for support.
We're working on an untethered version.

This is for Mac only. But you should be able to find (or work out
on your own) how to do it on Windows or Linux too.

-----------------------------------------------------------------------------
rslite
-----------------------------------------------------------------------------
This is an interface to the DFU and Recovery modes of the device. It
requires you to have libusb installed on your Mac.

Due to buggy interaction between libusb and the Apple device, any output
that is long gets all chewed up. But if you stick to just the "!" and
the "#" commands, you won't notice. We don't normally use this tool
but it's a lot easier to distribute and compile than the GUI we use.

The "!" (exclamation point, no quotes when you use it) sends a file.
The "#" (pound sign, no quotes when you use it) sends a script.
In both cases, you name the file right after the symbol.

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
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.
