You can actually attach desktop Safari's Web Inspector to both Mobile Safari and webviews running on a remote iPhone and get debugging, console logging, etc. The native stuff still has much better tooling, but the situation with webviews isn't as dire as you imagine.

Oh, that's nice! Looks like it's new with iOS 6. So, it was awful for a long time, but that is indeed a substantial improvement.
