FaceTime button replaces hold button?

Yes, it replaced the hold button. Mute does the same thing.

 

wouldnt mute be used to mute your voice, while you can still hear the other person if they are talking?

 

You can mute/volume I guess. I wonder is that button only shows up if the have a iPhone 4.

 

yes it will only be in iphone 4 as gm 4.0 have the mute button.

 

Not quite the same thing, but close enough to eliminate it.


HOLD - kills mic and speaker
MUTE - kills mic only


I've always thought there was a little redundancy in there too.

 

I'd rather keep hold and get rid of mute, but I guess there is no practical difference.
