iPhone 4S Has Been Jailbroken, Hack Enables Siri on iPhone 4
Diggester writes "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.
meh... they want to give people a reason to upgrade to 4S from 4
I think considering that the iPad 2, which has a faster processor than the 4s doesn't have Siri, this is a very strong probability.
I'd go much further. I'd say it's the only reason, and those postulating other reasons are deluding themselves. We're talking about Apple here. Style over substance. Fads over usefulness. Our way or the highway.
