Siri on iPhone 4: FAQ about Siri port *Update, now with screenshots!*



@jackoplane just tweeted some screenshots from his iPhone showing his Siri port. The Cydia icon in one of the screenshots indicates that it is indeed an iPhone 4, as the iPhone 4S hasn’t been jailbroken yet. We still hope to get a video that shows his port soon.

@joshmtucker just wrote an FAQ about their Siri port. Here’s a quick summary:

  • Screenshots should be posted very soon, a video is coming later today.
  • @iH8sn0w and @jackoplane are working on the port
  • It is not clear whether the port will be free or not.
  • A jailbreak of the device you want to install Siri is required.
  • There is still no ETA. But it will most likely be weeks, not days.

Here’s the full FAQ:

1. Who is currently working on this port?

At this current time, the people that are working on this particular port of Siri are Jack (@Jackoplane) and iH8sn0w. Joshua Tucker of ModMyi is the outside beta tester for this particular version.

2. What devices will be supported?

Currently, the port is being tested on an iPhone 4. However, the end goal is to port on all devices. At this time, we can not make any promises to when those will be, however the iPhone 3GS is looking promising outside of just the iPhone 4 at the moment.

3. Are we in need of any beta testers?

At this time, Jack and the team working on the port (including myself – beta testing wise) are not in need of any testers at this time. Asking if that is possible is not the best idea – if we do need more people, we will extent that opportunity out when the time comes.

4. When will this port be released?

We are not specifying an ETA at this time. The reason being is because we do not want to miss our expectation if we were to same something. Note that as soon as possible, we will release that information. For the time being however, there’s no decided or even thought up date for releasing this to the public.

5. How will this port be distributed?

There are numerous ways of distributing this particular port, however it’s a matter of how the files end up being compiled as well as cost. Cydia has been suggested many times and that is a viable option. However, we’re not limiting ourselves to just that venue as the tables may turn. At this particular moment in time, where this port will be distributed is currently undecided. Those of us that are hands-on with the work are always entertaining new ideas and will decide the venue when the time is right.

6. Will it be free or paid?

This is still undecided. This particular component is highly reliant on how we distribute this piece of software. Again, as the above, we’re thinking through it thoroughly to ensure the best for all. The reason why it may be required to pay (if not donate) is because there are hosting related costs that will need to be taken care of when the time comes.

7. When you say that there are “legal issues” to be deal with, what do you mean?

Because Siri is Apple’s product as well as copyrighted, one can’t just release these files and not get away with violating the law. When the news of Jack’s work as well as my involvement began, the files I had were strictly Apple’s. Thus, if we had given those files out then we could possibly be viable for copyright infringement and as many of you know from people like geohot, that’s no good in the hood.

8. What’s the current status of the port?

Because when we were first testing it and the legality of the whole ordeal, we’re are starting from the ground up. Re-writing code and that sort of thing to avoid copyright infringement. At this current stage, performance of Siri is just as good as on the iPhone 4S.

9. When will a video be released?

A performance video will be released tonight to show that the speed of Siri has been greatly improved. As for a full fledged video, that will be here in the next few days.

10. Is a jailbreak required to install Siri on a non-iPhone 4S device

Absolutely; no question.

11. Any update on the untethered jailbreak for iOS 5/iPhone 4S

We know nothing more than the public does. It’s not worth asking because we have absolutely no idea.

12. How does the Siri port connect to Apple’s servers?

When you first activate an iPhone 4S, when you enable Siri, Apple’s servers basically says “Oh, you’re an iPhone 4S. You’re clear.” Since we don’t have that luxury, we have to intercept the data that is being exchanged between devices to initially “trick” Apple’s servers into thinking that the device is authorized. So, imagine that what we have setup is a middle man.

iPhone 4 (in this case) sends out commands to Apple’s servers, we intercept and change the data, send to Apple’s servers, and Apple’s servers goes “Cool beans.”

13. What is required to host this type of capability?

We won’t really go into this because the process is not something that you can easily explain. However, as you guys have mentioned in chat, hosting this particular server to intercept data will cost money and will be the venue for all users to use Siri without an iPhone 4S.

14. Even though you can’t give an ETA, is it days, months, years, lifetimes, millenniums, never?


15. Is the authentication process made just one or every time?

Anytime you request from Apple’s servers, it performs a method of authentication.

16. What’s so special about the iPhone 4S and its connection with Siri?

There is nothing special about the 4S that makes it so that Siri can only work on that chip. Nothing is hardware accelerated in regards to Siri.

17. When you say that authentication is required, what does it take?

Not releasing this information at this time.

18. I want proof of the performance! How can I know that it is performing much better?

Here’s the video.
