The S60 Platform (formerly Series 60 User Interface) was a software platform for smartphones that runs on the Symbian operating system. It was created by Nokia in 2001, and was first released in 2002 with the Nokia 7650 smartphone. The OS platform has since seen 5 updated editions. Series 60 was renamed to ''S60'' in November 2005. In 2008, the Symbian Foundation was formed to consolidate all the assets of different Symbian platforms (S60, UIQ, MOAP), making it open source. In 2009, based on the code base of S60, the first iteration of the platform since the creation of Symbian Foundation was launch as S60 5th edition / Symbian^1. Subsequent iterations were named Symbian^2 and Symbian^3. S60 consists of a suite of libraries and standard applications, such as telephony, personal information manager (PIM) tools, and Helix-based multimedia players. It is intended to power fully featured modern phones with large colour screens, which are commonly known as smartphones. The S60 software is a multivendor standard for smartphones that supports application development in Java MIDP, C++, Python and Adobe Flash. Originally, the most distinguishing feature of S60 phones was that they allowed users to install new applications after purchase. Unlike a standard desktop platform, however, the built-in apps are rarely upgraded by the vendor beyond bug fixes. New features are only added to phones while they are being developed rather than after public release. Certain buttons are standardized, such as a menu key, a four way joystick or d-pad, left and right soft keys and a clear key. S60 is mainly used by Nokia but has also been used by a few other manufacturers, including Lenovo, LG Electronics, Panasonic, Samsung, Sendo, Siemens Mobile and Sony Ericsson. In addition to the manufacturers the community includes: * Software integration companies such as Sasken, Elektrobit, Teleca, Digia, Mobica, Atelier.tm * Semiconductor companies Texas Instruments, STMicroelectronics, Broadcom, Sony, Freescale Semiconductor, Samsung Electronics * Operators such as Vodafone and Orange who develop and provide S60-based mobile applications and services * Software developers and independent software vendors (ISVs). ==Editions== There have been four major releases of S60: "Series 60" (2001), "Series 60 Second Edition" (2002), "S60 3rd Edition" (2005) and "S60 5th Edition" (2008). Each release had an updated version called ''Feature Pack'', sometimes known as ''relay''. Each runs on a different Symbian version. ;Series 60 1st Edition: The devices' display resolution was fixed to 176×208. The Siemens SX1 meanwhile had 176×220. *Version 0.9 was the original and first shipped with Nokia 7650. *Version 1.2 (marketed as Feature Pack 1) first shipped with Nokia 3600/3650 in 2003. ;Series 60 2nd Edition: Also known as S60v2. *Version 2 was the original and first shipped with Nokia 6600. *Version 2.1 (Feature Pack 1) first came with Nokia 6620. *Version 2.6 (Feature Pack 2) first came with Nokia 6630. *Version 2.8 (Feature Pack 3) first started shipping with Nokia N70 in September 2005. FP3 now supports multiple resolutions, i.e. Basic (176×208), and Double (352×416). The N90 was the first Series 60 device to support a higher resolution (352×416). ;S60 3rd Edition: S60v3 uses a hardened version of Symbian OS (v9.1), which has mandatory code signing. In S60v3, a user may install only programs that have a certificate from a registered developer, unless the user disables that feature or modify the phone's firmware through third-party hacks that circumvent the mandatory signing restrictions. This makes software written for S60 1st Edition or 2nd Edition not binary-compatible with S60v3. *Version 3 was first introduced with Nokia N91 in 2005. *Version 3.1 (Feature Pack 1) first shipped with Nokia N95. *Version 3.2 (Feature Pack 2) first shipped with Nokia N78. :In 2006, a "Designed for S60 Devices" logo program for developers was launched. The logotype can be used with conforming programs regardless of them being native Symbian or Java. ;S60 5th Edition: In October 2008, S60 5th Edition was launched. It is sometimes called Symbian^1. Nokia skipped the number 4 as they traditionally always do (due to Asian tetraphobia).〔(S60 5th Edition and the Nokia 5800 XpressMusic are here! ), 3rd comment〕 S60 5th Edition runs on Symbian OS version 9.4. The major feature of 5th Edition is support for high-resolution 640×360 touchscreens; before 5th Edition, all S60 devices had a button-based user interface. S60 5th Edition also integrates standard C/C++ APIs and includes Adobe Flash Lite 3.0 with S60-specific ActionScript extensions that give Flash Lite developers access to phone features like contacts, text messaging, sensors and device location information (GPS). Despite the introduction of S60 5th Edition, the 3rd Edition continued to be marketed new as well, as 5th Edition is specially designed for, and exclusively available on touchscreens. *Version 5 was first introduced with Nokia 5800 XpressMusic in 2008. :The S60 5th Edition is the last edition of S60. Its assets along with Symbian OS, UIQ and MOAP(S) have been used as a base for Symbian, an open source operating system being developed by the Symbian Foundation. The first edition of Symbian, Symbian^1, uses S60 5th Edition on top of Symbian OS 9.4 as its base. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「S60 (software platform)」の詳細全文を読む スポンサード リンク
