Well, probably more in the sense of it generating recent contacts on its own without much control over them (as opposed to now when they can at least be disabled).
It's not much different to the phone.app with recents and favourites.....
iPhone 4S can't handle Handoff? That's the most dumbest excuse I've ever heard from Apple if this is true. There is literally no reason why it wouldn't work. Can't handle it my ass. Unless it relies on the same thing that AirDrop uses I guess.
Guessing it's because either BTLE or Wofi Direct is needed.
its not really an issue besides looking like crap for me but lets say you keep getting calls from a female coworker or whatnot and your wife is using your phone she might get suspicious for all those women showing up as your fave callers
That's a lame example lol.
