All the research reports from various research groups have a single conclusion, - Smartphones are happening and they rule the market. Technology advancements by smart phone vendors (Nokia, Sony Ericsson, Microsoft, Palm Etc), development support by Smartphone OS providers (Symbian, Microsoft, Linux Etc), evolution of mobile downloads provider (Handango, Nokia Software Market Etc), shift from voice centric offerings to value and data service offerings by mobile service providers have created a synergetic shift across mobile value chain. Mobile application developers too have made significant contribution by developing innovative mobile applications, utility tools, mobile games etc. End of the day, mobile users are the most demanding and benefited party in this mobile convergence revolution ...

Over the last decade we learned how to construct software systems using patterns that adhered to the concepts of object orientation. Now, service orientation requires us to adapt to a new approach to system integration and application development. However, at the moment most of us are still learning about this new technology and so we tend to apply familiar patterns when building Web services-based applications. Applying object-oriented patterns to service-based systems is generally a poor idea, since the scale of a typical object-oriented application (generally within a single enterprise or department) is dwarfed by the scale of a Web services-based application (which may span many enterprises and departments). It is crucial to remember that the use of SOAP and WSDL in our applications does not constitute service orientation.
