Shocker of a news! GeoHot is back with a bang with Limera1n jailbreaking tool to jailbreak iOS 4.1 on iPhone 4, iPhone 3GS, iPad & iPod Touch 3G/4G. It’s an untethered jailbreaking tool and can jailbreak iOS 4.1 as well as iOS 4.0. Please keep in mind that you will not be able to unlock if your baseband is higher than Ultrasn0w supported basebands.
Limera1n is a simple tool just like JailbreakMe and Spirit and doesn’t take more than 5 minutes to jailbreak the iDevice. I repeat, if you want to unlock then you must wait for Pwnagetool for 4.1 iOS and should not update to iOS 4.1 at any cost until unlock tool is released.
