Confirmed. Can we detect 400s with jsonp tho?

What I don't understand is why the doc says "Note: Prior to jQuery 1.5, this handler was not called for cross-domain script and JSONP requests" while the correct sentence is "Note: this handler IS not called for cross-domain script and JSONP requests" ;)

So, yes, the answer is no. jQuery doesn't detect HTTP errors for cross-domain script and jsonp requests as is (should be) documented.
