The iPhone Dev Team has been mighty busy as of late, updating their popular jailbreak tools with 5.1.1 Untether compatibly using the Rocky Racoon 5.1.1 Untether. The updates include PwnageTool 5.1.1, Redsn0w 0.9.12b1, cinject 0.5.4, and UltraSn0w 1.2.7.
If you've already jailbroken your device, and everything is working fine, they suggest, as do we, that you stick with your current jailbreak. If, on the other hand, you've experienced problems with tools like Absinthe, then you may welcome the addition of these updated tools from the iPhone Dev Team. Keep in mind that the underlying jailbreak is the same across all tools; they all utilize the Rocky Racoon untether where appropriate; the only difference is the way the exploit is injected.
