You are writing too much unnecessary jQuery code!

Try:  onclick="checkAllMsgsIn(this)"

Then:

> function checkAllMsgsIn() {
>         alert($('#msgCheckAllInbox').is(":checked"));    //Used to debug this

function checkAllMsgsIn(cb) {
  $('#msgsInbox input.messageCheckbox').attr('checked', cb.checked);
}

Much simpler.
