I have an hybrid application, it\'s basically a website running from the application folder inside a UIWebview.
The problem is that I was planning to update my websit
From the new text of of the application developer agreement, regarding downloading executable code:
The only exception to the foregoing is scripts and code downloaded and run by Apple's built-in WebKit framework.
This includes javascript and hybrid applications, so you should be fine.
Although, taking all of this into account, why didn't you just allow your app to take advantage of the iPhone webapp stuff? You still get an icon on the home screen, and get rid of the browser chrome without having to get Apple to approve your app.
