If you’ve already jailbroken an iOS device running the latest iOS 6.1 software using the tethered jailbreak, then you won’t need to restore it and perform the whole process again to get an untethered jailbreak later today when evasi0n drops. Although this is recommended, you will be able to convert your existing jailbreak into an untethered one using a simple tweak available through Cydia.

There weren’t many iOS 5.1.1 devices that the Absinthe 2.0 and Rocky Racoon jailbreaks didn’t support from day one, but one of them was the iPad 2,4 — the latest Wi-Fi iPad 2 that Apple released alongside the third-generation iPad earlier this year. Thanks to their latest updates, however, that’s all changed.

Shortly after the Chronic Dev-Team launched Absinthe 2.0 last Friday, Apple pushed out a revised iOS 5.1.1 (9B208) update for the iPhone 4. As yet, no other device has received the same update, and it’s unclear exactly what the software does. But if you installed it accidentally, you’ll be pleased to know that the Rocky Racoon untether now supports it.

As you probably know by now, today is the day that iOS hackers released the untethered jailbreak for devices running the latest iOS 5.1.1 software.

However, you may have already jailbroken yours using the tethered solution that was released some time ago. If that’s the case, you don’t need go through the whole process again — simply install the Rocky Racoon tweak to turn your tethered jailbreak into an untethered one.
