checked broken for radio buttons

Reproduced with both 1.6.3 and 1.6.4 - fine in 1.6.2.

Two radio buttons with second checked. onclick of first, attr("checked") still returns "checked" for the second.

Thanks for submitting a ticket. I've reviewed your test case and I believe you're incorrectly using .attr() rather than .prop() to check for the checked value. If you take a look here, a corrected version of your test case works fine with both jQuery 1.6.2,.3 and edge (.4).  http://jsfiddle.net/addyosmani/uvpAc/3/

See here for just one of the explanations behind .attr() vs .prop() (noting that this change was introduced in jQuery 1.6):  http://forum.jquery.com/topic/please-explain-attr-vs-prop-change-in-1-6

This is legit. We have the boolHook in place so that attr will work as it did before for booleans. We encourage people to use prop for boolean attributes, but attr should work as well until it is officially deprecated. I'm marking this ticket as a dupe of a later one.
