Good news. The iPhone 4S personal voice assistance Siri is compatible with the iPhone 4. The news comes from iOS hacker iH8Sn0w who posted a tweet saying that “Siri is not just compiled specifically for the A5 processor.”  This means that Siri can be install on other iOS devices such as the iPhone 4 or iPhone 3GS. Even though Apple says this is an iPhone 4S feature only, now we know that someone can work on this project and bring Siri to other iOS devices and release it on Cydia.
