The iPhone 4S is out and its new owners are not getting enough of Siri. And if you are an iPhone 4 users, then you will be glad to know that Siri may very well listen to your commands soon. If everything is well then you may also be able to install and use the voice based assistant to your jail-broken iPhone 4. It was being said that Siri has been developed only to work on the A5 processor but that may not be the case and Siri can also work on the A4 chip. Hackers are working on bringing it to iPhone 4 and iPod touch fourth-generation. So just wait until they are able to port it successfully to the A4 chip.
Keep in touch with us for more development on this.
