Hello i wanted to jailbreak my ipad2 which is now on 4.3.
Comex released a jailbreak for ipad 2 running 4.3.3.
Apple doesnt let us update to 4.3.3 anymore because it released 4.3.4
Do you have any idea how i can update it to 4.3.3?
Hey, don't download the update directly from itunes. Just search on the internet for the .ipsw file, which will be for the 4.3.3 version, then you can jailbreak it easily.
I'm sorry dude I didn't jailbreak any iPad ever, that's why I don't any experience. I'm into iPhones, and I think it's the same thing.. So..
Hope I helped you..

And yeah, I remembered, if you are running windows, and they ask for an update, don't press the update button, or restore.. ( I don't really remember its name..) press Shift + Restore and choose the .ipsw file.
It will not work unless you saved the SHSH blobs for 4.3.3
This is done automatically if you're using Cydia. If you have them saved, you can use TinyUmbrella to fake the certificate and successfully upgrade to 4.3.3, otherwise, it's a dead end.
Samer i cant save SHSH blobs for 4.3.3 because my ipad is not running 4.3.3 ! I tried saving shsh blobs for 4.3.0 but tinyumbrella says that im just too late and it cant be saved... I dont have a solution?
Sorry man but no you don't have a solution (at the moment). Since you do not have the SHSH blobs for 4.3.3, iTunes won't let you install it. You have to wait for a jailbreak for 4.3.4 or most probably for iOS 5.
I believe JailbreakMe does work for the 4.3.0 since the exploit hasn't been patched in versions under 4.3.4. So if it's a matter of upgrading for the newer firmware, i would hold out until a solid jailbreak is out. The iPad 2 ( i own one) is a very hard iDevice to crack till now :(
