I know when you set up an appointment with the Genuis bar they usually ask you to do the iOS Diagnostics thing, where they send you an email and ask you to follow the link, but is there a way of doing that solo? Maybe not going into the iOS Diagnostics, because I've tried that, and it doesn't work unless you have a ticket number. Is there an app you can get for the computer that will do the trick? Just to see what's going on, and clear RAM, etc. Nothing from the iTunes Store, that doesn't work, all those gimmicky apps. I want something that will actually do something for me.
