With their usual alacrity, those jovial hacker nerds over at the iPhone Dev Team have already jailbroken iOS 5. But there’s a caveat: it’s tethered only, for now. Also? Don’t even think about jailbreaking an iPhone 4S or iPad 2.
If you head on over to the Dev Team’s website, you can pick up the latest version of redsn0w, which will jailbreak and install Cydia on your iPhone 4, iPhone 3GS, iPad or iPod touch.
Tethered only, though, which means if you need to reboot your device, or if it runs on battery power, you’ll need to hook it up to your computer and run redsn0w again to restore it to jailbroken state.
Here’s another couple of things to know. If you’re using Ultrasn0w or Gevey SIM to keep your iPhone carrier unlocked, you probably should stay away from upgrading for right now, according to the Dev Team, although there are ways to restore while keeping your baseband intact.
As for the iPhone 4S and iPad 2, both devices run Apple’s new A5 processor, which is proving to be an absolute bitch to jailbreak. Only the iPad 2 can be jailbroken under iOS 4.3.3 using the userland JailBreakMe v3 exploit. If the iPad 2 is any example to go by, don’t expect the iPhone 4S to be jailbroken any time soon.
Look for our iOS 5 Jailbreak Superguide to be posted later today.
