I think it would be great to develop a native iPhone app (appStore based or for Jailbreak phones) that could select, download and run iPhone Web apps locally. I would see it similar to Installer, with sections and lists of available apps. You can then select an app, download it and it would basically download the website structure in a compressed file and store it locally in the iPhone.
The main screen of this app would be a list of installed Webapps and just clicking one will launch it in mobile Safari.
I think this would:
- Make Web apps much more useful by being able to run them offline
- Allow developers to develop local-like apps for the iPhone using the Web app framework which is much easier than the SDK.
