FOR IMMEDIATE RELEASE

Is the Smartphone the new personal computer? Six in ten people around the world now have cell phone subscriptions, far surpassing the quarter of the world’s population with a computer at home (according to a 2009 UN Report). Smartphones are cheaper than computers and more convenient because of their portability. And with profits from mobile applications growing, the continued subsidies of the hardware and operating systems by manufacturers, and carriers keeping new phones cheap or free, Smartphones will continue to be a practical alternative to computers for many people.

People are now using mobile phones for much more than calls. Phones are being used for web browsing, checking email, and accessing mobile applications. A rush of software developers has jumped on the mobile application development bandwagon. As Smartphones gain widespread adoption, Sarah Allen, author of Apress’s latest book "Pro Smartphone Cross-Platform Development: iPhone, Blackberry, Windows Mobile and Android Development and Distribution" explains that there are four major operating systems that make up over 90% of the market: Symbian, RIM BlackBerry, Apple iPhone, and Windows Mobile. The rest of the market is shared by Linux and the emerging mobile operating systems Google Android and Palm webOS.

For software developers looking to create applications on these operating systems, Allen outlines the programming language required to develop optimally for each platform.

Six Smartphone Operating System and the Corresponding Programming Language:

1) Symbian/ C++
2) RIM BlackBerry/ Java™
3) Apple iPhone/ Objective-C
4) Windows Mobile/ C#
5) Google Android/ Java™
6) Palm webOS/ JavaScript
