Afterwards, modified iRecovery to work with the iPod nano (had to add its DFU/Recovery USB ID) and allow it send files, and tested with some files I had extracted from the iPod nano 6G firmware (using the extract2g tool somewhere from http://www.freemyipod.org/ ).
disk.fw and osos.fw work (one boots disk mode, the other boots to a homescreen). The other files make the nano boot to a white screen, but go no further.
So, basically, it seems we can send encrypted firmware files to the iPod, and have them execute, similar to what is used to jailbreak the iPhone. If the nano rejects the file (i.e. unsigned, invalid), it reboots.
While this by itself isn’t that cool, hopefully the info will inspire someone else to finally hack this thing and give us custom ‘apps’.

iH8sn0w: Adding a new mode to sn0wbreeze. — http://twitpic.com/3k3mt6 (cleaning up the GUI a bit too).

firmware

Apple is on track to refresh the iPad by March and iPhone by late summer. A key component upgrade across these platforms will be a dual-core processor featuring a pair of 1GHz ARM Cortex A9 cores.

iPhone volumes could also be maintained at the 15 million/quarter level through next year. The launch at Verizon could support an incremental 8 million units.

The springboard hack is just the removal of a app and creation of a blank space. Not that amazing, but whats important is the bypass of Nano’s cache comparison, which compares any modded SB file and reverts it if it doesn’t like it, this opens up the possibility of hacking and modding, while not adding bootloaders or any of that fun stuff.

… in some of the device’s plists of reference to support of Movies, TV Shows, Apps, Games, vCards, Calender events and so on, with a few other cool things like a passcode lock. With the bypass I figured out, I hope to enable these pretty soon. It seems like the OS is a rehashed version of the previous Nano’s OS.

… the iPod Nano hasn’t been “jailbroken” as some sites claim, I do not have root access over the device. I did not “install” an app. I figured out how to remove them and insert a blank space into the springboard.
What I have also done is figured out a way for the iPod to boot with modified files (eg the SpingBoard Plist), bypassing the procedure it takes to stop this, I hope this will allow us to figure out a way to jailbreak it. I am primarily focusing on exposing some of the (for now) hidden features of the device.

Prepare the Media Server Before you install the actual plugin you need to prepare the Plex Media Server (it needed some tweaks before it would talk to the ATV). Since those changes are considered ‘beta’, you need to tell your PMS to download beta plug-ins, by enetering the following URL in a Safari running on the same machine as the media server: http://localhost:324…s/set?AS_BETA=1
After that start Plex and check for updates in the PlexOnline section.
Enable a higher Quality (optional) This part is optional, but if you feel like experimenting a lot, you might want to install a testing built of ffmpeg, that enables higher bitrates for the (currently) highest available quality (which is the only quality your ATV will use). This will also increase the image quality on other iOS devices, however you will need a potent Mac for the encoding! So If you still feel like installing use the following two commands in a Terminal on the Mac running your Media Server:
curl http://ambertation.de/downloads/PLEX/ffmpeg > ~/Downloads
/ffmpeg
cp ~/Downloads/ffmpeg ~/Library/Application\ Support/Plex/Plex
\ Media\ Server.app/Contents/Resources/
If you not use this, the plugin will still work, but the image-quality might not be on par with what you expect.
Install the Plugin First off: you need to Jailbreak your Apple TV. I suggest you use the Pawnage method. For the sake of the following instruction I assume thet the IP-Address of your ATV is 169.10.11.12, and that you can log in using ssh.

• Start your ATV and log in to your ATV using ssh ssh root@169.10.11.12
  It will ask you for your password, which (if you did not change the default) is alpine. (I strongly suggest you change the password using the passwd command!!!)
• In that ssh session, you need to add new cydia sources using echo "deb http://apt.awkwardtv.org ./" > /etc/apt
  /sources.list.d/awkwardtv.list
  echo "deb http://www.ambertation.de ./downloads
  /PLEX/" > /etc/apt/sources.list.d/plex.list
  
• Now update your cydia database using apt-get update
  
• Install the plugins (and its dependencies like beigelist by DHowett) with apt-get install plex-client-plugin
  
• Restart the GUI and hope that it comes back killall Lowtide
  If the UI does not come up again, you probably have to restore your ATV!

That is it. You should see the PLEX menu item now. If you experience any problems (which you almost certainly will ) just report back here. But remember the ATV is just a hobby
Updating the Plugin Once in a while I might release an updated version for the plugin, so once in a while you might want to check for updates and install them. Here is how that will work:

• Start your ATV and log in to your ATV using ssh ssh root@169.10.11.12
  
• In that ssh session enter apt-get update
  apt-get upgrade
  

• A MicroUSB cable
• iOS 4.2.1 for Apple TV
• PwnageTool 4.1.2 ( 4.1.3 is untested but could potentially work as well)

cp -r ~/Desktop/tethered/AppleTV2,1_4.2.1_8C154.bundle /Applications/
PwnageTool.app/Contents/Resources/FirmwareBundles/

unzip -j ~/Desktop/tethered/AppleTV2,1_4.2.1_8C154_Custom_Restore.ipsw
Firmware/dfu/iBSS.k66ap.RELEASE.dfu kernelcache.release.k66 -d ~/Desktop/tethered/

    cd ~/desktop/tethered
    ./tetheredboot -i iBSS.k66ap.RELEASE.dfu -k kernelcache.release.k66

• Connect your Apple TV with your Computer via microUSB.
• Now reboot your Apple TV by holding down Menu + Down buttons together for around 6 seconds.
• After reboot, immediately hold Menu + Play until you see the message in iTunes saying that Apple TV in recovery mode is detected.

I think I’m going to miss my Christmas deadline…

p0sixninja: @MuscleNerd no, the version leaked had one small change I did right before it was given to YOU and YOU only!!
p0sixninja: @MuscleNerd pod2g gave it to you in PM
p0sixninja: @MuscleNerd dude, you leaked it and tried to frame me to get pod2g to leave cdev, I’ve already heard it all
p0sixninja: SHAtter is burned, and now everyone knows why. Oh well, untether bootrom exploit is still on the way
MuscleNerd: @p0sixninja you never gave me a version
MuscleNerd: @p0sixninja please stop trying to bring up drama again. You always do this when you’re otherwise empty-handed.
MuscleNerd: @p0sixninja I believe one of the 15 people in that room leaked SHAtter because GP didn’t work on Mac at that point
MuscleNerd: @p0sixninja lol yes, that’s exactly why I would leak something that helps me more than anyone (unlock depends on jailbreak). Please think.

What's New in Version 1.0.2

MuscleNerd: Thanks to comex, redsn0w can now handle much bigger files than ramdisk 25MB limit. Useful for "backup plan" 4.2 untether
MuscleNerd: @jkurtz87 it shouldn’t require a restore…just another redsn0w run. (That’s the goal!)
