    Hello

    I own an ipad 2 64Gig 3G. My SHSH blobs are saved.

    I read somewhere even if you have the blobs you can't restore to 4.3.3 if apple releases 4.3.4.
    Because there is no bootroom exploit.
    This matters the 3G models only. Without 3G you can always restore to 4.3.3 with the saved blobs.

    Is this true?

    I am still not completely sure about the 3G blobs and stuff.

    I still have a few things to learn. :D

    If you had an iPad 1, I would say there is no problem, but I know there is something weird going on with iPad 2 3G.

    I have an iPad 1 64GB 3G too. So i thought i would be no problem if i have the blobs.
    Now i'm concerned. I develop apps for my own needs and i don't want to pay every year.
    I don't want to earn money with my apps so i need the jailbreak to run my apps.
    I own the iPad 2 from Day 1 and i like to use it for development too.

    Maybe someone can explain or confirm that's not possible to recover in case of 4.3.4 or 5 whatever.

    At the moment, if you have a 3G or CDMA model iPad2, it is NOT possible to use SHSH Blobs to downgrade or restore you device to anything except the current firmware (4.3.3 today). This is because Apple implemented a different type of check which comes AFTER the baseband is restored. A baseband downgrade will always fail, on the iPad2 this is catastrophic because there is no bootloader exploit which can be used to kick it out of recovery mode like you can on the iPad1.

    Therefore, if you make a serious mistake with your jailbroken 3G / CDMA iPad2, and Apple has released a new version of iOS, say 4.3.4, which patches the exploit, you will be out of luck. Your only option will be to restore to stock IOS.

    The simplest thing to do is stay where you are and jailbreak and DONT update, simple

    Yes but sometimes things go wrong and you have no option to do a restore.

    I'm still a little confused about that if I'm honest.

    I completely understand that if you upgraded to 4.3.4 you wouldn't be able to downgrade the baseband.

    However if you are on 4.4.3 and want to restore back to 4.4.3 your not actually downgrading anything.

    Can you just clarify this is not possible either?

    You won't be able to downgrade to 4.3.3 (please note the correct numbers) if, and ONLY if, Apple has stopped signing the 4.3.3.

    If they are still signing it - no problem, just go back to it.

    It's when they stop signing an iOS version that this comes into play. If you have to restore your device and Apple has stopped signing a jailbreakable version AND you don't have SHSH blobs (which you can't do on 3G/CDMA versions) - you can only restore to the Apple version.

    Example1: You are on 4.3.3, jailbroken with a 3G/CDMA iPad (can't save SHSH blobs). Apple has released nothing. For some reason, you have to restore your iPad. When you restore it, the only firmware version available for you to run on your iPad will be 4.3.3. You are very happy and simply re-jailbreak your iPad using the latest comex jailbreak. Done.

    Example2: You are on 4.3.3, jailbroken with a 3G/CDMA iPad (can't save SHSH blobs). Apple goes to 4.3.4 (which is not jailbroken). You sit tight. Then, for some reason, you have to restore your iPad. When you restore it, the only firmware version available for you to run on your iPad will be 4.3.4. Since you want to actually use your iPad, rather than look at it as a pretty paperweight, you have to put 4.3.4 on it. Then, it's back to waiting/hoping that someone can develop a jailbreak for that verison.

    Yeah, it's clear as mud, but hopefully this'll help...

    Now that was the explanation I was looking for. Thank you, Mickey330.
    With that one trick to enable multitouch without JB, I'm pretty happy. Although it bugs me that once I opened and closed an app, the folder the app is in is still open. That's what I really liked about JBing my iPad1 (without 3G).

    edit: I just found that tinyumbrella should now be able to save shsh blobs on 4.3.3 with 3G. If I read your post corrctly, I should now be able to go back to 4.3.3 even if Apple decides on releasing an update to 4.3.4, right???

    To go OT (just a little!) - take a look at the Cydia tweak FolderEnhancer. There is a setting (in the Settings) that allows a folder to "Close on App Launch." Works well. That's not all it does (can you say infinite number of apps/pages in a folder?), but at least it helps your gripe...

    Back on topic: Glad I could help.
