Said bug will force close the Calendar application whenever you try to edit a particular event, and it is definitely commendable to get that fixed before the phone actually rolls out to the market. Strangely enough, to fix a seemingly simple bug (to me anyways), the update does seem to weigh in at a rather hefty 26.59MB, making me wonder whether there is more than that which meets the eye.
It is only a few more days before the HTC EVO 3D is officially launched, so with news like this, you can't help but feel that your new purchase will be complete right from the get go.
