Hackers port Apple's Siri to iPhone 4 and iPod 4

Posted Nov 1, 2011 by Bradley Axmith
Hackers have given iPhone owners a taste of Christmas coming early by successfully installing Apple's premiere voice app, Siri, on older iPhones and iPods.
Software developers Steven Troughton-Smith and Grant Paul managed to get Siri to work on the older smartphone and iPod despite previous statements that only Apple iDevices endowed with the faster processor could handle demands of the voice app as it communicates with Apple's servers over WiFi or cellular networks.
Troughton-Smith who tweets his feats under @stroughtonsmith had previously port Siri onto devices running older chips but could not establish functional communication with Apple's servers, necessary for answering verbal queries.
In collaboration with Grant Paul, whose feats are followed at @chpwn, porting to Apple's servers was accomplished using software authentication tokens from a jailbroken iPhone 4S.
In other words, a hacked iPhone 4S provided the full source code that an older device used to disguise its iIdentity: Apple's servers recognised the 4S handshake and gave full functional access to Siri's databases.
"All I needed was access to a jailbroken iPhone 4S to put my hunch to the test. It literally took no longer than 10 minutes to put all the pieces in place and perform our first test on my iPhone 4, and it was an instant success," Troughton-Smith told, a Mac-fixated site that broke the news.
The Iphone Dev Team announced on 28 October a successful jailbreak of the new iPhone 4S, which allows the device to work with any cellular carrier in addition to gaining access to the Cydia store of unsanctioned applications developed by 3rd parties. It is expected to be available to the public soon.
According to the well-known hacking duo, the fourth generation iPod works less as efficiently with Siri due to its inferior built-in microphone.
The two developers will now try to port an iPhone 3GS to Siri's servers, which may encourage Apple to broaden official access to the voice app, which runs with the latest operating system, iOS 5. For now, Siri is just a beta version, which leaves hope for the millions of older iPhone owners salivating at the prospects of exploiting the 'humble servant's' services.
The Apple iPhone 4S is the company's fastest selling iPhone to date, selling more than 4 million units in its first weekend of release, compared to 1.7 million units of the iPhone 4 sold during its opening, according to PCMag.
