The infamous iPhone Dev Team is back on the scene once again to release new versions of redsn0w and PwnageTool to bring untethered jailbreak to iOS 4.3.1.

The untether exploit comes from Stefen Esser, a security researcher based in Germany. The 4.3.1 untether jailbreak works on following devices except for the iPad 2:

iPhone3GS
iPhone4 (GSM)
iPod touch 3G
iPod touch 4G
iPad1
AppleTV 2G (PwnageTool only for now)

According to the team, the reason the untether won’t "work as-is on the iPad 2 is that it requires a bootrom or iBoot-level exploit to install, and the iPad2 is not susceptible to either the limera1n or SHAtter bootrom exploits."

If you are using ultrasn0w, the dev team suggest that you don’t update yet.

"We need to first release an update to ultrasn0w that fixes some incompatibilities when FW 4.3.1 is used on the older basebands supported by ultrasn0w," says the team. " And remember once we do fix ultrasn0w for 4.3.1 (we’ll announce it here and on twitter), you must only get there via a custom IPSW from PwnageTool, Sn0wbreeze or xpwn! Don’t ever try to restore or update to a stock IPSW, or you’ll lose the unlock!"

The latest update of redsn0w and PwnageTool can be downloaded at the source link below.
