Since the iPhone 4S launched, we have been hearing about the Siri and its port to old generation devices of Apple. In the last couple of days, we have seen the successful Siri port on iPod touch and iPhone 4 by the efforts of iPhone hackers chpwn and Steve Troughton. Both hackers able to run and connect with Apple’s Siri servers from iPhone 4 hardware, while using the few files from the iPhone 4S core firmware and boot certificates of Apple’s new iPhone 4S.

Hackers just made us clear that Siri can easily and smoothly runs on the iPhone 4 and iPod Touch hardware, in short they proved that A4 processor is capable to run Siri on the device, but despite this, both hackers denied commenting on the public launch of the hack. Now after few days, chpwn said that they will not release the Siri hack on other iOS devices in public, because iPhone Dev Team has warned them and told us that the Siri hacks require Apple’s software piracy.

Here’s the main problem, which prevents the public launch of the hack. iPhone 4S Siri hacks require iPhone 4S firmware files that area available on the internet to download for all, but legally only those users can use those files that purchased the iPhone 4S. It means if you download and copy those files on your iPhone 4 or iPod Touch, you commit Apple’s software piracy, and this can easily get you in the big problem and the hacker too, same as geohot faced from Sony.

While the hackers said that Siri files are designed for A5 Processors, so you can download and legally use them on iPad 2, but as they have said before the actual hack requires a jailbreak on iOS 5 and on iPhone 4S to extract the files for the hack. As they have reported, A5 processor comes up with great firewall in the system, which prevents the hacker to jailbreak it on new firmware. So we have to wait for an untethered jailbreak on iPhone 4S and iPad 2, then we can expect the Siri port for iPad 2.
