So iOS6 is out, horrah. Now, it appears as though Apple have removed the \'Developer Console\' that used to exist in Safari. Great, I hear a lot of people say - it was limit
Looks like the built in console is gone. I tried plugging into a Windows 7 and opened Safari and could not locate the developer console. Then I read this article which confirmed it.
If you need to be able to test your site in both orientations then waterbug is not a good option, because it uses up the landscape orientation for its console view.
One decent option is to use Adobe Edge Inspect. You open your site on Chrome and open the app on your device and your device will mirror whatever page you have open on your desktop. Then you can use the Chrome dev tools to debug your content.
Like neno suggested, Telerik AppBuilder is a great applications. I am actually running Windows XP in a virtual machine on Linux only for the purpose of debugging my iPhone. Windows XP because in my case Windows 7 does regognize the iPhone, but iTunes and Telerik AppBuilder don't.
