Only buyers of the new iPhone 4S get the Siri voice assistant feature of iOS 5, but those who stay home and download iOS 5 for their iPhone 4 and iPhone 3GS will get the rest of the new features two days sooner. The 4S hits stores on October 14th, keeping with Apple’s tradition of Friday major retail launches. But the download version of iOS 5, a free gift from Apple to users of third and fourth generation iPhones, will surface online two days earlier on October 12th. As is the case with installing any new operating system on any piece of older slower hardware, some iOS 5 features will run more slowly on the iPhone 4 and especially the iPhone 3GS than they will on the new iPhone 4S which sports a significantly faster dual core processor.Only two headlining iOS 5 features, AirPlay Mirroring and Siri, require so much computing horsepower that they’ll only run on the latest iPhone and not the previous iterations. Of the two, only Siri will be widely missed…
Each new iPhone generation has its own “killer” feature around which Apple shapes its marketing campaign. For the iPhone 3G it was 3G networking, For the iPhone 4 it was FaceTime. For the iPhone 3GS it was… well, we’ll get back to you on that if we ever figure out what the 3GS was all about (we were merely jesting here, but several readers have accurately pointed out that the 3GS introduced both video and the compass to the iPhone timeline, for whatever it’s worth). But this time it’s unmistakably Siri for the iPhone 4S. Voice commands are nothing new, but they’ve long tended to be either overly simplistic or overly obtuse. Siri, based on the demos, puts a nearly human face on voice recognition. It also requires significant processing power to calculate in real time what it is the user it referring to and then come up with an appropriate answer or action. The iPhone 4 and 3GS, simply put, can’t do that. Apple is banking that despite all of the rest of the iOS 5 magic being given away to those users for free, the lack of Siri will drive at least some of them to end up buying an iPhone 4S after all. We’ll find out starting next week, as iOS 5 lands on Wednesday and the iPhone 4S with iOS 5 preinstalled hits stores on Friday. iPhone 4 and 3GS users, which way are you leaning on the iPhone 4S?
