The iPhone 4S is a touchscreen-based smartphone developed by Apple Inc. It is the fifth generation of the iPhone. It's the fastest, most powerful iPhone ever.
The iPhone 4S is a gradual step over the iPhone 4 improving the internals, but keeping the look and feel. Its fast, dual-core A5 processor coupled with its advanced operating system give this smartphone capabilities that have never before been possible.
It comes with a 3.5" screen with a resolution of 640 x 960 pixels, but on the inside there's a twice more powerful dual-core A5 processor. It also improves connectivity a notch, bringing 14.4Mbps HSPA download speeds. The iPhone 4s lets you record, edit and share stunning 1080p HD video. And it comes with iOS 5 and iCloud.
The Apple iPhone 4S is the next step in the evolution of the iPhone. Apple had already set the smartphone bar very high, and this device gives it a substantial nudge higher. The vast selection of iPhone apps continues to grow rapidly, expanding the phone's capabilities almost daily.
