    Having finally embraced jailbreaking (as opposed to dabbling and restoring to stock within hours) I was wondering what the options will be when Apple stops signing iOS 6 and you want to do a fresh install and jailbreak.

    For instance you install a dodgy tweak or you feel your phone is slowing down, and you want to restore to iOS 6 and jailbreak to start a fresh. Obviously Apple won't allow a restore to iOS 6 and right now blobs are no use.

    If you're using a 4S or i5 then you're out of luck currently till further notice from the dev team.

    Doesn't that kind of also disable all your tweaks/apps that are installed via Cydia too?

    Not yet, but 6.1.3 (or 6.2, depending on what they finally call it) will break the jailbreak, and will likely be out relatively soon.

    So if I want to restore and re-jailbreak my 4s now, can I?

    I guess I am confused by the previous comment that I am out of luck now.

    Does the signing window for 6.1.2 close right away when 6.1.3 is released?

    This has always confused me.

    My understanding of restoring iOS is that:

    1) iTunes contacts Apple to see if inserted iDevice is eligible for chosen firmware.
    2) If the signing window is open, Apple approves and sends back its approval in the form of a SHSH blob.
    3) iTunes reads this blob as a green light and goes ahead with the firmware restoration.
    Now when the window is closed, the SHSH blob reflects this and the restoration is denied or iTunes otherwise says "upgrade to x.x.x instead."

    You can use TinyUmbrella to save your green-light SHSH blobs. This is touted as being very important. That way when Apple releases future versions of iOS you still have your ticket into jailbreak land.

    Now this is where I've seen so many conflicting opinions and miscellaneous programs and yes/no's thrown out that I start to get a bit mixed up.

    Say Apple releases 6.1.3, and my jailbreak futzes up a month after. Is this where you use a program ("???") to essentially hijack/reroute iTunes' connection to Apple, returning the previously saved green-light SHSH blob you stashed months prior, and have iTunes see it and go "thanks mothership, I'll restore this iDevice now"? If no, why? Is there some other route you have to take, some other part to this I'm missing?

    Any clarification on how I might use this SHSH blob in the future would be great! Thanks, guys.

    They used to leave the signing window open for quite a while after the latest version was out, but the popularity of jailbreaking has since caused them to start closing it dang near instantly. I think I saw (via Twitter) that the window for the last release was less than a day.

    Not immediately. There's a slight overlap but that window is getting shorter and shorter with each new firmware release by Apple. If your plan is to restore to 6.1.2 one last time when the next firmware is released, I highly suggest you NOT do that. Its very likely the window will only be open for several hours. But if you want to do that and think you can make it happen, have at it. I don't know what your personal day to day life is like. I seem to always be at work when these things happen so I never wait for the next firmware release to restore. I either do it now or never, unless of course we get really lucky and MuscleNerd and the team release a tool to re-restore. But that's a whole nother story lol

    This sucks lol. I can't decide if I should restore once more before 6.1.3 comes out. It could be any day now. It wouldn't matter if we could downgrade using shsh's. Everything seems ok on my phone now except today I noticed that I was losing a bar of wifi every couple mins then it would go back to full even if I was standing right next to the router. I don't see how a tweak could effect that tho.

    When you restore coming from a jailbreak, even to rejailbreak, do you dfu restore?

    Why wouldn't it matter if we could re-restore with SHSH files? That's a huge benefit.

    Personally I always DFU restore as new, but its not absolutely necessary. You can just restore and it should be fine and then restore the backup or sync your content via the iTunes tabs or iCloud. Hope this helps.

    Also, if you think you're gonna want to restore one last time when 6.1.3 comes out, why not just do it now to be safe?

    Thats what I meant about shsh lol. None of this worrying about windows closing would matter if we could do that.

    Yes, now you can since 6.1.2 is the latest firmware out.
    Once 6.1.3 hits and Apple stops signing 6.1.2 you wont be able to restore to 6.1.2
    Just 6.1.3

    Oh haha. The way I read it was the complete opposite. Ill keep my fingers crossed on a re-restore tool. I have faith. If there wasn't a tiny sliver of hope I don't think the evaders would have stressed updating to iOS6.x via iTunes instead of OTA as much as they did. At least that's what I keep telling myself lol.

    That's the reason they had us restore using iTunes instead of OTA?

    As soon as Apple updates to 6.3 I'm going to simply charge my iPhone5 via a wall charger and not use iTunes whatsoever.

    And your point is?

    Plugging idevives to pc doesnt update your firmware.

    I'd think in the abundance of caution, but you know what? My idea is probably fairly lame.

    Memories though of losing my jailbreak because of some level of stupidity on my part (via iTunes) still haunts me.

    Just make sure you never press download and update when you plug into iTunes.
