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 came up with an Android equivalent to Siri called Iris (spell that backwards). It took them only 8 hours to have a working, if imperfect, app to play with and submit to the Android Market. This quick video review of Iris says the app is unpolished, but shows promise. For now, it generates some accurate results, and some amusing ones.
