Earlier today we reported that Apple's iOS 5.0.1 update today was the first iPhone 4S firmware build that’s both official and has an accessible encryption key for its main file system, thus meaning that browsing the device’s main file system with your PC is now possible. From a later tweet by iOS hacker @MuscleNerd, it seems that Apple has made a Siri port legally possible with today’s iOS 5.0.1 update by offering open access to system files that were previously encrypted.
MuscleNerd, a figurehead in the iOS jailbreaking and hacking community, tweeted today that the iOS 5.0.1 update from today made iOS 5 on the iPhone 4 "(to clarify: wide open for inspection from a Mac/PC...not wide open security wise :) Can get Siri files and such without piracy)". Previously, to legally run Siri, one would have to have access to an iPhone 4S unique identifier, and the key would need to be rotated every 24 hours to avoid being detected. If a large enough number of these devices start calling on Siri from one 4S identifier, Apple will be able to see the activity and kill the port permanently.
No one really knows why Apple has left such a wide opening for hackers to exploit when the notion of a Siri port has been such a hotly discussed item as of recent. We'll keep you updated when whether there're further updates from Apple about Siri, or development fron third-party groups and developers.
