    Really? I've looked up on downgrading 4G but everywhere says you can't, I used to downgrade my 1G all the time, but this is different.. I think?

    Unfortunately MadClaw, you cannot get an untethered jailbreak for your iPod touch 4G just yet. (This upcoming release of redsn0w will use part of 4.2b3 for an untethered jailbreak, so if you don't have its SHSHs you're out of luck.) You are also correct that you may not downgrade your iPod touch 4G due to the SHSH check.

    I was confused about this actually, I've got an iPod Touch 4G on 2.4.1 because I accidently, and stupidly, RESTORED and upgraded. So now I'm stuck...a few questions:

    1) I know I can tether jailbreak it but what exactly are the cons of this method?
    2) Will this redsn0w jailbreak that is going to be released work for me or just people with the SHSH's on their device?
    3) What's happening with Comex and his final proper release of 4.2.1 jailbreak?

    1) You cannot reboot your iPod without connecting to a computer and using redsn0w to boot jailbroken. This is fine for an iPod since you'll just put it to sleep most of the time but could be annoying if you are going away from a computer for a week or so and accidently reboot. A few explanations on what this means. Respringing is not the same as rebooting and is not affected. If you have SpringBoard tweaks (e.g. scrolling board, winterboard etc.) the iPod will freeze on the Apple logo. If you do not have any of these then your iPod will boot but no jailbroken apps will work.

    2) You need the SHSH for 4.2.1b3 available (I got them with Tinyumbrella before Apple stopped signing) So no, you can't use this untether.

    3) My guess is that its proving a lot more hassle than he originally thought. As this method doesn't burn any more holes (reveal more exploits to Apple) They've decided to release this one to tide us over.

    Thanks [​IMG]

    Well, time to play the greatest game of all....waiting. [​IMG] Although, a tethered jailbreak is extremely tempting if I don't say so myself >.

    The iPod still boots if its tethered jailbreak but rebooted without rejailbreaking? Interesting, I always thought that with a tethered jailbreak your iPod simply wouldn't work if it got turned off.

    Well I've just jailbroken my iPod Touch 4G perfectly fine on 4.2.1, tethered of course but I don't need to turn it off, just put it on sleep.

    If you've got ANYTHING that manifests in the Settings program (i.e. integrated with Springboard) then it won't. And let's face it: That's where all the fun is.

    A tethered jailbreak won't boot if you install anything that uses Mobile Substrate (SBsettings, Winterboard, SBrotator, etc.) But for some reason, my iPod wouldn't boot with only [Redacted] (maybe because of Appsync)

    Almost certainly AppSync. That tricks iTunes into thinking cracked apps are legally bought to back them up so must use Mobile Substrate and Springboard in some way.

    So i'm currently on 4.1 and i want upgrade to 4.2.1. How can i backup all of my stuff, so that i have the complete same content on my updated device. Only by clicking on backup in itunes? I don't want to lose all of my save stats in games and everything else.

    ^ It is a beta version (full of bugs and not "official")

    @Sotoro: You don't have to restore to go to 4.2.1. When you click the update button, you just get an update, that's it. You don't lose anything (aside from your jailbreak)
