iPhone 4S is the fifth generation of iPhone developed by Apple Inc. The latest smartphone retains the exterior design of its predecessor, iPhone 4, but features some important upgrades compared to the previous model.
Perhaps, the most prominent features are Siri, a voice-recognition feature that allows users to control their phones by talking to them, cloud-sourced data and an improved 8-megapixel camera system. It also has a 3.5-inch TFT Retina multi-touch display and is loaded with the latest Apple operating system iOS 5.
However, it doesn't have some highly expected specs like edge-to-edge design, a larger display, 4G LTE and Near Field Communication (NFC) technology.
Meanwhile, Lumia 800 is Nokia's first mobile phone to run Windows Phone OS as a part of the first wave of Windows Phone devices to be released by the company. The latest smartphone from Nokia features a 3.7-inch AMOLED ClearBlack curved display blending seamlessly into the reduced body design and a 1.4 GHz processor.
Lumia 800 contains an instant-share camera experience based on leading Carl Zeiss optics, HD video playback, 16GB of internal user memory and 25GB of free SkyDrive storage for storing images and music. The latest Windows Phone OS-powered smartphone is expected to arrive in North America in early 2012.
