One of the main selling points of the iPhone 4S would be the curiosity to check out Siri, the voice-recognition system which receives spoken commands and processes it, delivering some rather hilarious results at times, but for most of its part, it does commendably well. The i4Siri is a project that intends to make available Siri to other devices that run on the iOS, other than the iPhone 4S. Basically, we are looking at the iPhone 4, the iPhone 3GS, and the first two generations of the iPad. i4Siri supports features such as time, timer, notes. ‘smart’ Siri, Internet search, dictation, phone calls, jokes, alarms, weather, “Where am I?”, and Wolfram Alpha. You can find out how to install i4siri on your non-iPhone 4S device here if you are curious enough. Alternatively, just get the iPhone 4S to avoid jumping through so many hoops.
