You are green with envy because your Apple iPhone 4 doesn't have the updated 8MP camera, dual-core A5 processor and Siri functionality that your buddy's Apple iPhone 4S has. You can't do anything about the first two items, but there just might be a way to get Siri to do her thing on your iPhone 4. A developer by the name of Steven Troughton-Smith was working on a hack that would allow Apple's new voice-activated personal assistant to work on the Apple iPhone 4 and found the last piece of the puzzle that he was working on inside a jailbroken Apple iPhone 4S.
The result is a 20 step, 10 minute process that uses proprietary files from the latest version of Apple's touchscreen smartphone. As a result of the proprietary nature of the iPhone 4S files used in the hack, Troughton-Smith tweeted that he will not distribute the fruits of his labor over Cydia for fear that he might "anger the hive". All is not lost, however, as the developer promised that once a jailbreak solution is available for the Apple iPhone 4S, he will post notes about his work.
