Apple has repeatedly rejected the idea of the personal assistant being ported to older iPhones citing reasons such as inferior hardware in the older models.
Roberto Martinez, an employee at an AT&T store in Holyoke, Mass., said that, “the only way Siri will operate properly is with a dual core processor allowing it to do multiple things at a time.” Adding a quad core processor, Martinez stated, would enhance Siri and allow it to reach its full potential. Unfortunately, there are no current plans (at least a public one) to build a future iPhone with a quad core processor.
Although Apple claimed that the hardware in older iPhones would not support Siri, hackers have long discovered that hardware inferiority isn’t the reason for not making the personal assistant available on the iPhone 4, iPhone 3GS and iPad 2. There have been many successful Siri ports onto previous iPhones.
The issue with releasing a Siri port becomes one of legality. Up until recently, the only way for hackers to obtain the necessary files to port and connect Siri to Apple’s servers were to illegally copy files and authorization keys from an iPhone 4S and transfer them onto the non-4S device.
Much to the surprise of the jailbreaking community, Apple made it possible to legally obtain these files when they allowed access to decrypted system files in their iOS 5.0.1 update.
Since then, hackers have been hard at work in an attempt to design a tool that would allow Siri to be activated on older iPhones.
Notable iOS hacker chpwn has released such a tool he named Spire. This software legally ports Siri onto older iPhone devices. However, as chpwn mentions in his blog, “Spire is not a complete solution. Apple still requires authorization to use Siri, so information from an iPhone 4S is still required.”
Of course there’s a workaround to this obligation, which Chpwn addresses in his blog, but that would require hacking into an iPhone 4S’ internals and setting up a proxy server.
Loyal iPhone customers felt slighted when Apple released the new personal assistant and made it exclusive to the new iPhone 4S. Everyone wants Siri on their phone. As Martinez indicated, “I rate Siri 9 out of 10 not because of its functionality but more because of its humor and creativeness.”
