Redsn0w 0.9.8b3 was updated today to tether jailbreak the latest firmware iOS 4.3.4. This lets iDevice users to jailbreak their devices on the latest firmware by Apple. But today i0n1c has announced some bad news, i0n1c mentioned on his Twitter that untethered jailbreak for iOS 4.3.4 is not coming soon.
After all the news heard about jailbreak, it seems that untethered jailbreak is not possible till the release of final version of iOS 5. When it will be possible to jailbreak iOS 5 final version, then users would prefer to update to the shinny iOS 5.
Important Note : We advice you to stay away from upgrading to iOS 4.3.4 (specially iPad 2 users) so that you could enjoy untethered jailbreak 4.3.3.
