zhiing is developed for all 5 of the top mobile platforms - Blackberry, iPhone, Nokia, Windows Mobile and Android.  Blackberry and iPhone are live and the others will be available soon.  Today zhiing works on every network except the walled garden of Verizon (we are working to fix this too).  Cross platform, and cross network is the key to the evolution of usage of zhiing - it needs to work from every mobile to every mobile in order to become a successful location messaging system

The forces shaping the evolving mobile ecosystem are comprised of multiple carriers and stakeholders, as well as consumer electronics and device OEMs, major online search and independent application software vendors.

Meanwhile, operators are accelerating service and application development to seamlessly work across fixed and wireless networks and devices. An increasingly large number of subscribers will rely on next-generation networks to drive process and service innovations.

These new market dynamics are driving a fundamental shift in business and architectural models for operators. Operators need to develop and deploy appropriate platforms, architectures, interfaces, protocols and business models that allow them to monetize their networks and increase profitability. To be successful, they must optimize their network infrastructures to provide a robust ecosystem of applications via open networks, rapid service creation and a high-quality user experience in the very near future.

Furthermore, the race is on to develop the best handset, and the best mobile operating system.  Mobile browsing is a horrible experience that is only used when absolutely necessary - so porting your website to mobile is not a huge strategic effort - developing an application to run on mobile devices needs to be considered strategy.
