Hum, I don't remember where I found something on it, sorry...
But I recently did an update to 3.6 where I had to patch the files again - all you have to do is to search for

$vbulletin->options['editthreadtitlelimit'] * 60) > TIMENOW)

You will find that in editpost.php and in ajax.php (I _think_ these were the only two).
There will be an if clause similar to that one

if ($getpost['postid'] == $postinfo['postid'] AND $edit['title'] != '' AND ($postinfo['dateline'] + $vbulletin->options['editthreadtitlelimit'] * 60) > TIMENOW)

All you have to do is to remove the last AND condition where it checks whether the edit is within time limit or not.

That's what I did....
