ibCom has sponsored Konstant Info. (India) to build a simple iPhone application for managing and interacting (email, SMS, viewing in maps) with person contacts. It is a real usable application, but just importantly serves as a demonstratable example.
The development has been completed and final testing in readiness for submission into the App Store will happen later this week.
Once in the App Store, the source code will also be available as a base for building an iPhone application.
If you have a need know, you get started by doing the design and using the services of Konstant Info (contact vipin@konstantinfo.com). They can work off an a design document as per attached. It is optional to provide the screenshots - but if doing a new design you can use them and edit them with mark up on top to help communicate the application needs. Konstant Info. can guide you through the process of getting your application into the Apple App. Store etc.
Of course you can develop yourself or source a developer through Freelancer.com (or alike) and it could just as easily be a Android or Windows Mobile 7 based application.
Applications like these can really help engage users that aren't sitting in front of a desk and with the touch/gester based operating systems that usage is much more "human".
eg
plumber/locksmith adding an order
service person adding time on job (including gps/location based integration)
etc...
