With the dual-core A5 chip, all-new 8-megapixel camera and optics, iOS 5, iCloud, and Siri, iPhone 4S is the most amazing iPhone yet.

iCloud stores your music, photos, documents, and more and wirelessly pushes them to all your devices. Automatic, effortless, and seamless - it just works.

Siri on iPhone 4S lets you use your voice to send messages, set reminders, place phone calls, and more.
