Note: iOS 5 may not be available for some users yet as usually these things take a while to propagate thoughout all regional iTunes stores. iOS 5 is compatible with iPhone 3GS, iPhone 4 and iPhone 4S, third- and fourth-generation iPod touch, as well as both iPad 1 and iPad 2. However, some features are resource-intensive and thus only available on recent devices. Note that Siri, an intelligent personal assistant users can converse with, remains exclusive to iPhone 4S for the time being.
