Hey guys, sorry if this question is asked often.

I have an iPod Touch 4G that I had jailbroken on 4.2.1, but I messed with some system files that I shouldn't have messed with and I had to restore and update to 4.3. Is there anyway I can downgrade to 4.2.1 so I can jailbreak again?

Yeah you can if you have a backup that isn't the current update. Also you can manually install any version of the firmware that is compatible with the phone.

I've followed the steps and now I am looking for the etc folder from the go menu in finder but when I search its not there??
 
At this point im just frustrated. I changed the host file with this ip 74.208.105.171 gs.apple.com Then I followed all the steps and got 4.2.1 on. When I went to jailbreak, I got it into DFU mode but the jailbreak failed. Now I just want to update to 4.3 but I cant because I dont remember what I changed and replace with this 74.208.105.171 gs.apple.com. Anybody know the original text so I can update to 4.3?
 
How many times did you try the jb and what were you using? Pwnage or greenpoison? Just because the jb fails once doesn't mean that it was a disaster. Try the jb again.

Tried it with Greenpois0n and it failed so I tried it with Redsnow and it worked. It's tethered, but thats no big deal as I rarely ever turn it off. But now what do I do with the host file? I deleted what I added and now it looks like this. Is this correct?

Like I said before, I use tiny umbrella instead of editing my host files, so I don't know what it's supposed to look like.
