Unless their chipset has already been exploited and jailbroken on a previous device, it takes a lot of time for the iOS jailbreaking community to jailbreak for a new iOS device. The iPhone 4S and iPad 2, both of which are based on a still unexploited dual-core A5 chip, haven't received a jailbreak for iOS 5 yet. However, it appears they'll be getting one soon, as a certain eminent iPhone hacker has let us know that the iPhone 4S has jailbroken, and a jailbreak for the iPad 2 is in the works."In related news, Hackers have succeeded in bringing a limited port of Apple's new Siri voice assistant feature onto jailbroken versions of the iPhone 4 and the fourth-generation iPod touch.
