Hey everybody.

I was just wondering how far this "sandbox" thing goes. Say I make an app that lets you transfer files to your iPhone (kinda like airsharing, briefcase, etc) and then I make another app that wants to read those files and do something with them. Is this possible at all, and I mean officially? I know that it's not really supposed to but you know how you can set up an app url protocol like myapp://filename.extension or something like that? Something that safari could handle. Basically it's like how you go into safari and type tel://yournumber and it sends it to phone.app to call that number. well what if i set up a webview in my app to retrieve my other app (airsharing-type)'s files. Thanks in advance.

sure it works, but then your app is gone, and the other app has control!

With firmware 2.0.x, any App could read and write files anywhere in
/private/var/mobile/Applications

With firmware 2.1 it doesn't work.
You are restricted to /private/var/mobile/Applications/YOUR_APP_UUID

If you have a jailbroken phone and install the app in /Applications you can read and write anywhere you want.

The only way I see this working is if the first application stores all the data (that is to be used by the second application) on a server.
