Smartphone

Wikipedia: 
smartphone is a high-end mobile phone[1][2][3] which combines the functions of a personal digital assistant (PDA) and a mobile phone. Today's models typically also serve as portable media players and camera phones with high-resolution touchscreensweb browsers that can access and properly display standard web pages rather than only mobile-optimized sites, GPS navigation, Wi-Fi and mobile broadband access.
The term smartphone is usually used to describe phones with more advanced computing ability and connectivity than a contemporary feature phonealthough the distinction can be vague and there is no official definition for what constitutes the difference between them.


A feature phone is typically based on proprietary firmware, while a smartphone runs a more open and complete mobile operating system.[2] Widespread examples of smartphone operating systems are Apple's iOSGoogle's AndroidMicrosoft's Windows Phone 7Nokia'sSymbianRIM's BlackBerry OS, and embedded Linux distributions such as Maemo and MeeGo.


Smartphones can run third-party applications using advanced application programming interfaces (APIs).
Allthough most of today's feature phones are also able to run third-party applications, for example mobile games, these applications are based on rather limited platforms such as Java ME (a virtual machine) or BREW (a pseudo-OS for native code).[1] A smartphone mobile appintegrates more tightly with the user interface and other phone features than a feature phone application, and relies on a more powerfulapplication programming interface (API).[4]


In 2000, the touchscreen Ericsson R380 Smartphone was released.[9] It was the first device to use an open operating system, the Symbian OS.[10] It was the first device marketed as a 'smartphone'.[11] It combined the functions of a mobile phone and a personal digital assistant (PDA).
