The iPhone Dev-Team has released RedSn0w 0.9.8b3 which can perform a tethered jailbreak on iOS 4.3.4. This means that you will have to connect your device to a computer and run redsn0w each time you restart.
For the convenience of kernel hackers like @comex and @i0n1c, we have a new redsn0w 0.9.8b3 that supports a TETHERED jailbreak for iOS 4.3.4 on all devices that have 4.3.4 except the iPad2. The vast majority of people will want to stay back at 4.3.3 because that's where the untethered jailbreak is! There are no new features in 4.3.4 - only fixes for jailbreak exploits.
Also, this is a good time to remind everyone (since we're still seeing confusion about this): iPad2 owners with a baseband (3G or CDMA) cannot currently use saved blobs to go back to 4.3.3 once the signing window is closed. This is unlike every other device, so don't be confused! iPad2 owners with basebands should stay away from all updates to maintain your jailbreak!
This jailbreak works with iPhone 3GS, iPhone 4, iPad 1, iPod Touch 3G and iPod Touch 4G. It does not work with iPad 2.
You can download RedSn0w 0.9.8b3 from here: (Mac, Windows)
Famous iPhone hacker Stefan Esser, also known as i0n1c, recently wrote on twitter that we should not expect untether jailbreak for iOS 4.3.4 anytime soon. i0n1c was the one who created untether for iOS 4.3.3firmware.
Our advice is simple - save your 4.3.3 SHSH keys asap. With these SHSH keys you will be able to restore to iOS 4.3.3 anytime, without - only iOS 4.3.4. Here are tutorials for you.
