What's also pleases me when you miss a call flashes the right button and you know when the screen is from the one who missed a call, and when you press a button with a large image display which a call was missed.
what I think is a pity that's you if you want fast times in a row where the call the phone a little hot so 2 -3 sec. Until it shows the redial that you can dial the number again. That would ichgedacht it can handle those new phones faster.
