Redsn0w Untethered iOS 4.3.3 Jailbreak Released For iPhone, iPad, iPod touch

The iPhone Dev Team has released updated version of both Redsn0w and PwnageTool tojailbreak iOS 4.3.3 untethered using i0n1c’s untethered exploit.

UPDATE: Jailbreak for Verizon iPhone 4 running iOS 4.2.8 is also available.

… 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:

• iPhone3GS
• iPhone4 (GSM)  
• iPod touch 3G
• iPod touch 4G
• iPad1
• AppleTV2G (v4.3 8F202)
