I have iPad2 Wifi 4.3.3 JB. If I upgrade to 5.0.1, as is now recommended, can I complete that operation, then go back to 4.3.3 and re-JB? The question is... will the action of upgrading to 5.0.1 now be or any use at a future time when the JB is made available, but go back in the meantime? Or would I be stuck in 5.0.1 until the next JB?

I thought I understood enough of this stuff to figure it out on my own, but I guess not. It seems (in my feeble mind) that if I have blobs for 5.0.1 - which I thought I could obtain just by running Tiny Umbrella or something now, I could get to that point whenever I wished.

Thanks.

You should be able to go back down to 4.3.3 if you have your blobs saved.

No graywolf, that is very bad advice. Blobs CANNOT be used on iPad2 for 5.x firmwares.

OP, if you choose to go this route you must stay on 5.0.1 when you install it as once the singing window is closed you cannot install it again, even if you have saved blobs.

That means you will be without a jailbreak until one gets released!

See here - IOS5 Jailbreak Strategy Guide

iPad 2 is too confusing. If you have 3g then you cant do this and that, if you are on 5.x you cant to this....

I'm lost, I thought blooms could be used to downgrade from ios5 back to 4.3.3 on an ipad2 3G?

Blobs not blooms lmao

I disagree - If you are JB on 4.3.3, and your blobs are saved (they should be at a minimum w/cydia), then you are safe to upgrade right now to 5.0.1. If the jailbreak never comes to be on 5.0.1, you can always downgrade back to 4.3.3 and re-jailbreak. The risk people are facing right now is if Apple was to immediately stop signing 5.0.1 and issue firmware 5.0.2 or 5.1(or if you just missed the window), and you were still on 4.3.3 - even though you had blobs save for 5.0.1, as it stands right now, you could not get back to 5.0.1......only 5.0.2 or whatever the new firmware is.

You can only downgrade though by using tinycfw if your iPad 2 is GSM, if it's CDMA then I believe there is no option to do so.
