It seems that Apple team has not enough team to fix @i0n1c’s untethered exploit which was first used to jailbreak iOS 4.3.1 then iOS 4.3.2. Recent iOS 4.3.3 update which fixes location database bug is still vulnerable to the exploit. redsn0w 0.9.6rc15 has been released to support untethered jailbreak for devices running iOS 4.3.3.
Here is what iPhone Dev Team says about recent release
… three in a row! Apple released iOS 4.3.3 on Wednesday, and once again the untethered jailbreak exploit that@i0n1c created for 4.3.1 still works. That makes it an unprecedented three firmwares where the same userland exploit works. We’re not exactly sure why Apple hasn’t fixed the hole yet, but we’re not complaining!
Today’s PwnageTool and redsn0w incorporate @i0n1c’s port to 4.3.3 (it’s ironic that such a long-lasting untether doesn’t even have an official name!). It also of course uses geohot’s limera1n bootrom exploit to inject the jailbreak. The 4.3.3 untether works on all devices that actually support 4.3.3 except for the iPad2:
- iPhone4 (GSM)
- iPod touch 3G
- iPod touch 4G
- AppleTV2G (v4.3 8F202)
Some things to note:
- ultrasn0w unlockers must stay away from redsn0w! Use only a custom IPSW to update to 4.3.3, to avoid updating your baseband.
