Look who's calling
Every time you make a call or your friend gives you a ring, you get to see your friend's
latest social network status update right on the call screen. You'll also see a birthday
reminder if your friend's birthday (stored on your phone or online account) will
happen in a few days.
Viewing a task reminder while on a call
Did you promise to babysit for a friend this weekend? If you associate a task to a
contact, you'll see a task reminder on the call screen when you're on a call with that
friend.
If the contact has a recent status update, you won't be able to see the task
reminder.
