The operating system was unveiled with the iPhone at the Macworld Conference & Expo, January 9, 2007, and released in June of that year.At first, Apple marketing literature did not specify a separate name for the operating system, stating simply that the "iPhone runs OS X".Initially, third-party applications were not supported. Steve Jobs' reasoning was that developers could build web applications that "would behave like native apps on the iPhone".
On October 17, 2007, Apple announced that a native Software Development Kit (SDK) was under development and that they planned to put it "in developers' hands in February".On March 6, 2008, Apple released the first beta, along with a new name for the operating system: "iPhone OS".Apple had released the iPod Touch, which had most of the non-phone capabilities of the iPhone. Apple also sold more than one million iPhones during the 2007 holiday season.
On January 27, 2010, Apple announced the iPad, featuring a larger screen than the iPhone and iPod Touch, and designed for web browsing, media consumption, and reading iBooks.In June 2010, Apple rebranded iPhone OS as "iOS". The trademark "IOS" had been used by Cisco for over a decade for its operating system, IOS, used on its routers.To avoid any potential lawsuit, Apple licensed the "IOS" trademark from Cisco.
By late 2011, iOS accounted for 60% of the market share for smartphones and tablet computers.By the end of 2012, iOS accounted for 21% of the smartphone OS market and 43.6% of the tablet OS market.
Updates in ios:
Apple provides major updates to the iOS operating system approximately once a year over iTunes and also, since iOS version 5.0, over the air. The latest version is iOS 7.0.6, which is available for the iPhone 4, iPhone 4S, iPhone 5, iPhone 5C, iPhone 5S, iPad 2, the third-generation iPad, the fourth-generation iPad, the iPad Air, the first-generation iPad Mini, the second-generation iPad Mini, and the fifth-generation iPod Touch. The update was released on February 21, 2014.
Before iOS 4's release in 2010, iPod Touch users had to pay for system software updates. Apple claimed that this was the case, because the iPod Touch was not a 'subscription device' like the iPhone (i.e., it was a one-off purchase).Apple said it had 'found a way' to deliver software updates for free to iPod Touch users at WWDC 2010, when iOS 4 was unveiled
Windows Phone (abbreviated as WP) is a series of proprietary smartphone operating systems developed by Microsoft. It is the successor to Windows Mobile,although it is incompatible with the earlier platform.With Windows Phone, Microsoft created a new user interface, featuring a design language named "Modern" (which was formerly known as "Metro").Unlike its predecessor, it is primarily aimed at the consumer market rather than the enterprise market.It was first launched in October 2010 with Windows Phone 7.
The latest release is Windows Phone 8, which was launched in October 2012. Windows Phone 8 will be succeeded by Windows Phone 8.1, which was released in preview form to developers on February 10, 2014
Generations of Windows phone:
Windows Phone 7 :
Windows Phone 7 was announced at Mobile World Congress in Barcelona, Catalonia, Spain, on February 15, 2010, and released publicly on November 8, 2010 in the United States.
Windows Phone 8 :
On October 29, 2012, Microsoft released Windows Phone 8, a new generation of the operating system. Windows Phone 8 replaces its previously Windows CE-based architecture with one based on the Windows NT kernel with many components shared with Windows 8, allowing applications to be easily ported between the two platforms.
Symbian is an open-source (EPL) mobile operating system (OS) and computing platform designed for smartphones and currently maintained by Accenture. Symbian was originally developed by Symbian Ltd.,as a descendant of Psion's EPOC and runs exclusively on ARM processors, although an unreleased x86 port existed. The current form of Symbian is an open-source platform developed by Symbian Foundation in 2009, as the successor of the original Symbian OS. Symbian was used by many major mobile phone brands, like Samsung, Motorola, Sony Ericsson, and above all by Nokia. It was the most popular smartphone OS on a worldwide average until the end of 2010, when it was overtaken by Android.Symbian rose to fame from its use with the S60 platform built by Nokia, first released in 2002 and powering most Nokia smartphones. UIQ, another Symbian platform, ran in parallel, but these two platforms were not compatible with each other. Symbian^3, was officially released in Q4 2010 as the successor of S60 and UIQ, first used in the Nokia N8, to use a single platform for the OS. In May 2011 an update, Symbian Anna, was officially announced, followed by Nokia Belle (previously Symbian Belle) in August 2011.
On 11 February 2011, Nokia announced that it would use Microsoft's Windows Phone OS as its primary smartphone platform, and Symbian will be its franchise platform, dropping Symbian as its main smartphone OS of choice.On 22 June 2011 Nokia made an agreement with Accenture for an outsourcing program. Accenture will provide Symbian-based software development and support services to Nokia through 2016; about 2,800 Nokia employees became Accenture employees as of October 2011.The transfer was completed on 30 September 2011.The Nokia 808 PureView is officially the last Symbian smartphone.
BlackBerry OS is a proprietary mobile operating system developed by BlackBerry Ltd for its BlackBerry line of smartphone handheld devices. The operating system provides multitasking and supports specialized input devices that have been adopted by BlackBerry Ltd. for use in its handhelds, particularly the trackwheel, trackball, and most recently, the trackpad and touchscreen.
The BlackBerry platform is perhaps best known for its native support for corporate email, through MIDP 1.0 and, more recently, a subset of MIDP 2.0, which allows complete wireless activation and synchronization with Microsoft Exchange, Lotus Domino, or Novell GroupWise email, calendar, tasks, notes, and contacts, when used with BlackBerry Enterprise Server. The operating system also supports WAP 1.2.
Updates to the operating system may be automatically available from wireless carriers that support the BlackBerry over the air software loading (OTASL) service.
Third-party developers can write software using the available BlackBerry API classes, although applications that make use of certain functionality must be digitally signed.
Research from June 2011 indicates that approximately 45% of mobile developers were using the platform at the time of publication.
BlackBerry OS was discontinued after the release of BlackBerry 10, but BlackBerry will continue support for the BlackBerry OS.
