Remember I posted under .3 regarding charger plug release and trunk release. I actually have had .13 since may 22. Try it now.
here's the real detailed use case: I have an older kid that gets his shoes on really fast. Meanwhile I'm helping a toddler put on shoes. Older kid is eager to get in car and is waiting in front of the door. He can't open it until I unlock the car. I'm still busy with shoes.
With my fob, it's pretty easy to reach in pocket and doubleclick, then continue with helping toddler get dressed. With phone, meh, the other kid can just wait.
