my bad, guess i wasnt specific enough.
theres two things that could be done
1. a web app
theres some free stuff on the apple developer site that shows you how to make a site that will look good on safari on the iphone. This is free and easy to do cause ns is already web based, but theres not as much you can do and its not as good as a real app
2. app store app
ns drops $100 to be an app store developer and builds an app that can be run off the iphone. its a better interface and would have more features like uploading photos, but it costs money, its a brand new platform to learn and you have to go by apples guidelines. You have less freedom cause everything has to go through apple
id be happier either way, happer with an app store app, but a web app is easier for you guys
