Redsn0w Lite


     There has been many updates in the jailbreaking world. New versions and releases for Jailbird, SweetTooth, and bluesn0w looming over the horizon, everyday there is something new that surprises me. I was extremely surprised when I woke up this morning and checked my SMS. I had Twitter mobile alerts for the redsn0w project and my eyes widened as I read the message. I tapped on the url ( and that opened up the My eyes quickly scanned the page for any changes in content. That’s when I found it, the iPhone Dev Team has released an iPod touch 2G jailbreak. The jailbeak is for the new 2.2.1 firmware and it’s a tethered jalibreak.

     Currently it’s codenamed “redsn0w lite” because it is not the complete program. For those of you who don’t even know what “tethered” means, I recommend just completely staying away from jailbreaking as of now. Everytime you reboot your iPT2G you have to rejailbreak which is why it shouldn’t be used by beginners, or even intermediate users. Experts should be the only ones using this right now. The iPhone hackers are working on a untethered jailbreak and the ETA is unknown, and here is their README.

     Please note: the team says they will not be giving ANY type of support for the jailbreak. They have clearly stated many, many times (on their blog, on the redsn0w project page, and other places) that it is for advanced users ONLY. If you know/think you’ll mess up or have doubts about this, you shouldn’t even download their program. Even experts will have trouble with this. If you are brave and willing enough to do this, there will be a guide (hopefully within a few days) in our guides section for tethered jailbreaking iPT2G. One other thing I forgot to mention, the jailbreak currently only runs on Mac. Until then, Windows users I guess you’ll just have to wait patiently.

     If you are REALLY sure you can do this and you’re willing to try this now, here are the instructions provided by the iPhone Dev Team. Or else just wait until a friendly guide is up:

Basic instructions
Note: these are the bare bones instructions.   Please don't come to us
looking for more detailed instructions.

1) Copy the FirmwareBundles and CustomPackages directories into
   your 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.

     Also be on the lookout for Jailbird (custom IPSW builder for Windows, with the same functionality as PwnageTool for Mac) private beta is coming out soon. There should be a submission form on to request a copy of the private beta.
