If you didn’t save SHSH blobs for your device with TinyUmbrella you wont be able to restore, downgrade or upgrade your device to this firmware version. As you probably know Apple has decided to release an upgrade to their mobile iOS couple of days ago. The main reason for this upgrade was to block easy jailbreaking through the jailbreakme.com website, as this jailbreak was able to jailbreak even iPad 2 which was impossible to jailbreak with other tools like RedSn0w, PwnageTools and other.
Also users which decided to experiment with iOS 5 beta will have trouble downgrading their device. Again, if they weren’t careful enough and didn’t save SHSH blobs on their devices they wont be able to downgrade to 4.3.3. Good news for them is that they still can downgrade the firmware but unfortunately they will be able to restore only to iOS 4.3.4.
iPhone Dev Team has published an updated version of RedSn0w jailbreak which is able to jailbreak 4.3.4 firmware but the jailbreak is only a tethered one, meaning that every time you turn of your device you’ll need to boot it up through the same RedSn0w jailbreaking process.
If you didn’t upgrade your device yet, you shouldn’t do it at all. At this moment this update wont benefit you in any way, as it doesn’t introduce any improvement. The only reason Apple has upgraded was to block users from jailbreaking their devices. SO if you care about the jailbreak and unlock do not upgrade! Also it is highly advisable to save the SHSH blobs on your device while it is still possible. You can find instructions on how to use TinyUmbrella for this in our blogs archive, alongside with many instructions and guides for jailbreaking and unlocking your iPhone or iPad.

Famous iPhone Dev Team has finally announced that RedSn0w jailbreak software was updated to support jailbreak for iOS 4.3.3. It seems that Apple, because of circumstances like the iphone tracking bugs hasn’t had enough time to patch the jailbreak exploit so far. This means that the same jailbreak works for the third time already! This is great news for all iphone users who own iPhone 4 (AT&T), iPhone 3GS, original iPad and iPad Touch (3G and 4G). Apple TV 2G is also on the list of supported devices. However the jailbreak for iPad 2 is still not available and we have no clue when will it be available. It seems that so far iPad 2 has been to big of challenge for jailbreak developers. Lets hope this will change sooner rather than later!
Meanwhile you can download RedSn0w jailbreak and use it to jailbreak your iPhone.
