If you’re an iPad 2 owner, now’s the time to rejoice, as you device can be jailbroken through the easiest method available. I’m talking about JailbreakMe 3.0, developed by the famous @comex. You don’t even have to connect your iDevice to a PC, just access www.jailbreakme.com and that’s it.
Supported devices include the iPad 1 (4.3 to 4.3.3), iPad 2 (4.3.3), iPhone 3GS (4.3 to 4.3.3), iPhone 4 (4.3 to 4.3.3), iPhone 4 CDMA (4.2.6 to 4.2.8) and iPods – iPod touch 3g (4.3, 4.3.2, 4.3.3), iPod touch 4g (4.3 to 4.3.3). This jailbreak method doesn’t rely on the limera1n exploit, but on a userland one.
This means you’re almost totally safe, but you can still damage the device after you get root access. Jailbreakme is very easy to reverse, through an iTunes restore and it’s even approved by the US authorities.
