Of all the upgrades that distinguish the new iPhone 4S from its predecessors, probably the feature that's gotten the most attention is the voice-based personal assistant app called Siri, which allows a user to accomplish certain tasks almost entirely by voice. A few days ago, as reported by TechCrunch, a team of Android developers has come up with an Android equivalent to Siri called Iris (spell that backwards), and that it took them only 8 hours to have a working, if imperfect, app to play with and submit to the Android Market. This says the app is unpolished, but shows promise. For now, it generates some accurate results, and some amusing ones.
