Check http://iwebinspector.com It's using your idea, it's a simple tool to use it

actually not work for me. I've added the method on ApplicationDidfinishLaunchin...... (Xcode gives me a warning, I think it's normal) I can see the page listing, but the inspector doesn't report errors or warnings etc... If I open the page using the chrome inspector I see all the log. It's really frustrating (dbugging javascript in the uiwebview)

Do you use right iOS SDK? Do you have iOS SDK 4.0 in parallels?

It's normal that works on Chrome since it's based on WebKit too :)

Thanks much for the tip, this is exactly what I was looking for!!
