    Alright so I'm going to open this up to everyone to see if it actually works or not. I did this last night at 1 am and now I'm at work so I lack a few details but here goes:

    For those that don't have their SHSH blobs saved, like me (I chose not to, yeah I know), and you want to restore your ipod touch if its on an unsigned firmware, or downgrade then you may wish to try this.

    Go to the finder on the dock, right click and select go to folder. Once there go ahead and type in /etc. That should take you to where you can find the host file. Make a copy of the host file and place it somewhere it won't get lost, deleted, or modified, you'll need this to be able to download updates again from apple. After you've backed up the hosts file, go ahead and open it up with admin permission. Somewhere toward the bottom you will see the apple ip. Go ahead and delete that line but leave a space holder there with a single tap of the space (that's what i did so i'll leave it the same for you guys to either test with no space holder or with). After that close it and save the file. If it won't let you save. Copy the hosts file to the desktop, modify it their and copy it back. It should ask you to authenticate and you must do so.

    From here plug your ipod in, and open itunes. Make sure you've saved your music, data, etc. I will not be held responsible for your deleted data.
    THIS WILL DELETE EVERYTHING. I WILL SAY IT AGAIN, THIS WILL DELETE EVERYTHING. If you are just restoring and have a back up great, if not, and you are downgrading you will have nothing on your ipod so it will have to be synced all over again.

    After plugging in, you can option click restore and select the firmware you want to restore to, or downgrade to. I was in DFU mode when I did this so it may not work in recovery mode. If someone wants to test both and let me know I'll change it here. I'll make this a guide as soon as I can replicate the results when I get home in 8 hours, in both modes, but for now I want to just throw it out their for comments. So enter DFU mode by holding down the power/lock button and the home button for 10 seconds,then release the power/lock button and continue to hold the home button, your ipod should power down and restart with a black screen and iTunes will say something along the lines of an ipood has been detected in recovery. If you have an iTunes logo on your ipod youre in recovery mode and need to try again. Then you can option click and select the firmware again. At the top where it has the update status it should act as if it is authenticating, if it looks like its freezing it is not. I freaked yesterday but it worked. I have a clean install now, which is what I wanted.

    Alright so warning, I will not be held responsible for any damage or bricking or whatever you do to your ipod/iphone. I have done this only once and will try to replicate the results tonight and if it works, I will edit this into a guide. Right now if anyone wants to test this and let me know and confirm it, then I will turn this into a guide while I'm at work. Just thought that it might be useful since I know my SHSH blobs weren't saved and somehow deleting the ip address managed to keep Apple from authenticating while I was connected to the internet. Be aware of the risks, and please comment. I want to know if this actually works for people. One thing I might mention is that my iTunes is not current, I'm running a 2nd gen 8 gig itouch, and I did not downgrade. I simply restored a jailbreak from 4.2.1 to 4.2.1 but I did it in DFU mode. Before I edited the host file, iTunes would not allow me to restore or DFU it, saying that my ipod was not eligible for the restore.

    Cheers

    iPod 2G will not support anything newer than 4.2.1. Nothing really revolutionary here.

    This is great, thank you so much. A great guide for people like me who need to downgrade their firmware. Have you tried this with recovery mode? I need to do the same thing, but the power button on my ipod is broken.

    I'll try it in recovery mode later today. But for now, does anyone know of any programs that will put my ipod touch into full DFU mode? I know some programs can put the ipod into DFU mode, but it's not "full DFU." Thank you.

    Tried it in recovery mode. Didn't work. Just got the message that my ipod is not eligible for the selected build.

    This is an error which means you are attempting to downgrade. You require SHSH blobs to downgrade to preferred firmware.
