Live Voicemail
Apple is also adding old-school answering machine style call screening to the Phone app. When somebody leaves you a voicemail, you won’t have to wait for it to show up in the Voicemail section; instead, you’ll get a live transcript of the message as they leave it directly on the incoming call screen. You can use that to decide whether to pick up the call or just let them finish leaving the message.
The iPhone app is also blending voicemail into the Recent calls list; you’ll see if somebody left you a voicemail message directly below the missed call, saving you a trip over to the separate Voicemail tab.
