Android from Google Inc.[24] (free and open source)
Android was developed by a small startup company that was purchased by Google Inc., and Google continues to update the software. Android is a Linux-derived OS backed by Google, along with major hardware and software developers (such as Intel, HTC, ARM, Samsung, Motorola and eBay, to name a few), that form the Open Handset Alliance.[26] Released on November 5th 2007, the OS received praise from a number of developers upon its introduction.[27] Android releases prior to 2.0 (1.0, 1.5, 1.6) were used exclusively on mobile phones. Most Android phones, and some Android tablets, now use a 2.x release. Android 3.0 was a tablet-oriented release and does not officially run on mobile phones. The current Android version is 4.0. Android releases are nicknamed after sweets or dessert items like Cupcake (1.5), Frozen Yogurt (2.2), Honeycomb (3.0), and Ice Cream Sandwich (4.0). Most major mobile service providers carry an Android device. Since the HTC Dream was introduced, there has been an explosion in the number of devices that carry Android OS. From Q2 of 2009 to the second quarter of 2010, Android's worldwide market share rose 850% from 1.8% to 17.2%. On 15 November 2011, Android reached 52.5% of the global smartphone market share.[28]
BlackBerry OS from RIM (closed source, proprietary)
This OS is focused on easy operation and was originally designed for business. Recently it has seen a surge in third-party applications and has been improved to offer full multimedia support. Currently Blackberry's App World has over 50,000 downloadable applications. RIM's future strategy will focus on the newly acquired QNX, having already launched the BlackBerry PlayBook tablet running a version of QNX and expecting the first QNX smartphones in early 2012.[29]
The Apple iPhone, iPod Touch, iPad, and second-generation Apple TV all use an operating system called iOS, which is derived fromMac OS X. Native third party applications were not officially supported until the release of iOS 2.0 on July 11th 2008. Before this, "jailbreaking" allowed third party applications to be installed, and this method is still available. Currently all iOS devices are developed by Apple and manufactured by Foxconn or another of Apple's partners.
Symbian OS from Nokia and Accenture[24] (open public license)
Symbian has the largest share in most markets worldwide, but lags behind other companies in the relatively small but highly visible North American market.[30] This matches the success of Nokia in all markets except Japan. In Japan Symbian is strong due to a relationship with NTT DoCoMo, with only one of the 44 Symbian handsets released in Japan coming from Nokia.[31] It has been used by many major handset manufacturers, including BenQ, Fujitsu, LG, Mitsubishi, Motorola, Nokia, Samsung, Sharp, and Sony Ericsson. Current Symbian-based devices are being made by Fujitsu, Nokia, Samsung, Sharp, and Sony Ericsson. Prior to 2009 Symbian supported multiple user interfaces, i.e. UIQ from UIQ Technologies, S60 from Nokia, and MOAP from NTT DOCOMO. As part of the formation of the Symbian OS in 2009 these three UIs were merged into a single OS which is now fully open source. Recently, though shipments of Symbian devices have increased, the operating system's worldwide market share has declined from over 50% to just over 40% from 2009 to 2010. Nokia handed the development of Symbian to Accenture, which will continue to support the OS until 2016.[32]
This is a mobile operating system being developed by Samsung Electronics. Samsung claims that bada will rapidly replace its proprietary feature phone platform, converting feature phones to smartphones.The name 'bada' is derived from 바다, the Korean word for ocean or sea. The first device to run bada is called 'Wave' and was unveiled to the public at Mobile World Congress 2010. The Wave is a fully touchscreen phone running the new mobile operating system. With the phone, Samsung also released an app store, called Samsung Apps, to the public. It has close to 3000[33] mobile applications.
Samsung has said that they don't see Bada as a smartphone operating system, but as an OS with a kernel configurable architecture, which allows the use of either a proprietary real-time operating system, or the Linux kernel. Though Samsung plans to install bada on many phones, the company still has a large lineup of Android phones.
Windows Phone from Microsoft (closed source, proprietary)
On February 15th, 2010, Microsoft unveiled its next-generation mobile OS, Windows Phone. The new mobile OS includes a completely new over-hauled UI inspired by Microsoft's "Metro Design Language". It includes full integration of Microsoft services such as Windows Live, Zune, Xbox Live and Bing, but also integrates with many other non-Microsoft services such as Facebook andGoogle accounts. The new software platform has received some positive reception from the technology press.[34][35][36]
webOS is a proprietary mobile operating system running on the Linux kernel, initially developed by Palm, which launched with thePalm Pre. After being acquired by HP, two phones (the Veer and the Pre 3) and a tablet (the TouchPad) running webOS were introduced in 2011. On August 18th, 2011, HP announced that webOS hardware is discontinued[37] but HP will continue to support and update webOS software and develop the webOS ecosystem.[38] HP plans to open-source webOS in the future.

MeeGo from non-profit organization The Linux Foundation (open source, GPL)
At the 2010 Mobile World Congress in Barcelona, Nokia and Intel both unveiled 'MeeGo' a brand new mobile operating system which would combine the best of Moblin and the best of Maemo to create a truly open-sourced experience for users across all devices. As of 2011, Nokia has announced that it will no longer be pursuing MeeGo and will instead adopt Windows Phone as its primary mobile OS. Nokia announced the Nokia N9 on June 21, 2011 at the Nokia Connection event[43] in Singapore. The phone is presumed to become available to the public in September 2011. LG announced its support for the platform.[44]
Linux is strongest in China where it is used by Motorola, and in Japan, used by DoCoMo.[45] Rather than being an OS in its own right, Linux is used as a basis for a number of different operating systems developed by several vendors, including Android, GridOS, Boot to Gecko, LiMo, Maemo, MeeGo, Openmoko and Qt Extended, which are mostly incompatible.[46][47] PalmSource (now Access) is moving towards an interface running on Linux.[48] Another software platform based on Linux is being developed by Motorola, NEC, NTT DoCoMo, Panasonic, Samsung, and Vodafone.[49]
Brew is used by some mobile phone manufacturers and mobile networks, however most often the end-user does not know this since mobile phones running Brew most often lack any Brew branding. Brew runs in the background with the custom "skins" of the mobile phone manufacturer or operator on-top. Brew is used by Sprint Nextel, metroPCS, U.S. Cellular and Verizon in the US and by the Three network in much of Europe, the UK and Australia on many mobile phones produced especially for their network. Manufacturers such as LG CDMA, Huawei, INQ Mobile, Amoi, and Samsung Mobile amongst others use Brew in some of their mobile phones and it is featured in Three UK phones such as the 3 Skypephone, INQ1 and Huawei u7510 (3 Touch). Two of HTC's mobile phones use Brew's successor Brew MP.

Windows Mobile from Microsoft[24][51] (closed source, proprietary)
The Windows CE operating system and Windows Mobile middleware are widely spread in Asia. The two improved variants of this operating system, Windows Mobile 6 Professional (for touch screen devices) and Windows Mobile 6 Standard, were unveiled in February 2007. It has been criticized for having a user interface which is not optimized for touch input by fingers; instead, it is more usable with a stylus. However, unlike iPhone OS, it does support both touch screen and physical keyboard configurations.
Windows Mobile's market share has sharply declined in recent years to just 5% in Q2 of 2010.[52] Microsoft is phasing out the Windows Mobile OS to specialized markets and is instead focusing on its new operating system and software platform, Windows Phone.
