In case you’re living under the rocks and don’t know, Siri has been ported on iPhone 4 and iPod touch 4G and successfully connected to Apple’s servers. Yes! Both developers chpwn and stroughtonsmith were able to get Siri fully working on older devices so everyone started to ask about ETA. Unfortunately, Siri for iPhone 4 and iPod touch 4G won’t be released right now for some reasons explained below.
The well-known developer chpwn published a new blog post to explain the reasons why they can’t release the instructions to install Siri on iPhone 4 or iPod touch running iOS 5 and get it connected to Apple’s servers.
The reason is because Apple owns the copyright on the software, images, and data used inside iOS. Siri files which should be extracted from the iPhone 4S’ or from its iOS 5 IPSW are copyrighted to Apple. No one can copy, distribute, adapt or modify these files.
What’s the legal method do that? Well, you can do that only if you have an iPhone 4S. You can get the files out of your iPhone 4S and put it on your iPhone 4 or whatever device you want to run Siri on. And sure if you already own an iPhone 4S, you already have Siri.
Just from that, you currently must already own an iPhone 4S to install Siri on it without a blatant copyright violation. But even that’s not all: if you do all of that, there’s still a few more reasons why Siri won’t just work.
There’s also another method to get Siri on older devices:
The issue with the second method is more technical: the firmware files are distributed encrypted, and we do not yet have the decryption key to access the Siri files inside of the iPhone 4S firmware file.
However, there is still hope. Siri on older devices can be installed once an iPhone 4S jailbreak is released:
When we have the ability to decrypt the encrypted iPhone 4S firmware file — to extract the Siri files legally, without the need for an iPhone 4S — and we have an iPhone 4S jailbreak to obtain the other necessary information at a mass scale, hopefully this can become a reality and everyone can try out Siri on their older devices. Until then, showing you a video that it is possible is the best we can do.
Now let’s hope the iPhone 4S jailbreak is released soon!
