Installing Siri on iPhone 4 has a significant progress. One of the bigger pieces of news coming today from the key-person of iPhone Dev-team, MuscleNerd. As most of you know that Apple released today a tweaked version of iOS 5.0.1 for iPhone 4S only, with minor updates. But from hackers’ vision, iOS 5.0.1 new build has opened the horizon for porting Siri to iPhone 4 legally, let’s see what MuscleNerd tweeted.

MuscleNerd (1st tweet):

Huh…today’s 4S 5.0.1 bump (9A406) has wide open main fs

MuscleNerd (2nd tweet replying to someone) :

it’s the first public 4S ipsw where the main filesystem keys are obtainable (due to non-encrypted ramdisks)

MuscleNerd (3rd tweet to clarify) :

(to clarify: wide open for inspection from a Mac/PC…not wide open security wise 🙂 Can get Siri files and such without piracy)

MuscleNerd is announcing that the new decrypted ramdisks in iOS 5.0.1 new build will allow them to write simple script to legally extract the needed files to port Siri to iPhone 4, 3GS, iPod touch 4G, 3G without the need of such jailbreak apps like H1siri that may violate your privacy.

The reason for this violation of privacy was that H1siri routed traffic through their own servers instead of Apple’s meaning they could use that connection to obtain user information. These new decrypted ramdisks will allow the legal port of siri on non-iPhone 4S devices, hence the traffic will still be routed to Apple servers which guarantee user privacy.

Stay tuned for more news as it happens!
