Android application development

I want to develop a android and iPhone application which should work for most of the android and iphone operating system.  The application is required for on the spot inspection of vehicle, when I inspect the vehicle I will enter details of my observation and photos of that vehicle. This record should be saved for each vehicle on mobile so that whenever required in future we should be able to view all details by entering the vehicle number. Also this data should be uploaded to a web server on shared web hosting where we can view the details online anytime by logging into website. The data should be transferred automatically to the server through GPRS of mobile available. The photos should be taken by the camera of mobile through application and saved in the application for that vehicle.
