Nokia is buying the 52% of Symbian that it didn’t own, and spinning off the mobile software company into a new entity called the Symbian Foundation. Sony Ericcson, Motorola and NTT DoCoMo are the other partners in a long-needed effort to reunite the various forks of the world’s most popular mobile phone operating system. AT&T, LG, STMicroelectronics, Texas Instruments. and Vodafone have commited themselves to the new effort. Samsung is also expected to join the foundation. See this article from the Associated Press for more information.

The platform wars are heating up in the mobile phone industry. It is very difficult for a mobile carrier to support several different handset operating systems. Vodaphone CEO Arun Sarin estimated that his UK-based company supports 30 or 40 different OSes, according to this MacWorld UK report. Sarin is also quited in this Business Week article.

It takes a great deal of effort to establish a computing standard. Consider Apple, which became a new entrant with its iPhone. There are about 4 million Apple iPhones available or in use now, which is a respectable number when one considers its limited availability. There are no official iPhone providers in China or Japan yet, for example.

Google won’t make or market its own mobile phone, especially now that the company has dropped out of the 700 mHz auction, as reported by Forbes. The company’s Android mobile phone platform is based upon Linux, and over 30 companies have signed on to develop and support Android hardware. Prototypes of the Google phone were shown in Frankfurt at the Mobile World Congress this week. This CNET slideshow starts with a pic of one such prototype, which appears to be running and connected to a GSM network.

Microsoft used a similar approach to develop its Windows Mobile platform for PDAs and smartphones. The company expects that 20 million Windows Mobile phones from various manufacturers will be sold in the first half of 2008. None of these phones are Microsoft-branded devices.

Symbian claims to have the top spot, with 77 million units sold in the last year. Nokia is the main manufacturer that uses the Symbian operating system, along with Sony Ericsson. The latter company has started using Windows Mobile in its high-end smartphones, however.

From Forbes: developers are readying programs that will actually run on the iPhone, instead of just in the Safari web browser. There’s a wide variety of web-based applications available, but these programs don’t offer the speed and features that an application that is actually running on the iPhone could provide. Web-based applications also have to respect firewall and security rules in order to access any Web-based data.

Apple has not released a Software Developers Kit (SDK) that contains tools that help programmers access the iPhone’s resident applications like the address book and calendar.

Windows Mobile, Palm and Symbian mobile phones do run applications directly. The operating system developers released SDKs long ago.

Apple has maintained strict control over the iPhone application market through the company’s exclusive agreements with mobile carriers. Carriers either want to sell the iPhone or sometime like it, as I discussed on 13 January 2008. It’s widely assumed that Apple will let programmers sell their iPhone applications through iTunes, which is the management software for iPhone users. Ars Technica revealed that an iPhone application installation key – a very long string of numbers – has been identified by some programmers and released on the Internet as an image file.

Of course, Apple would take a percentage on any software sold through iTunes. The Forbes article mentions 30 percent as a possible fee. As Marc Hedlund pointed out last November, the Sidekick uses a similar business model. As a Sidekick user, I agree with Marc – I hate paying for features on my phone. The Sidekick 3 doesn’t include a world clock, for example. Users have to navigate to the phone’s download screen and buy a clock.

One of the Sidekick’s original developers, Andy Rubin, now works for Google on its Open Handset Alliance project. I mentioned the project on 5 November 2007. Here are some other articles about the rumored gPhone.

There are third-party iPhone applications available, of course. Some of these are designed to unlock the iPhone, or to add an application installer feature.

But Apple can break these unauthorized applications or change the application installation key at any time by updating the iPhone firmware, as I mentioned on 26 January 2008.
