The Coolest Feature of iPhone 3GS

Voice Control
Apple has given 3GS owners the ability to control their phone via simple voice commands, relayed through a glitzy Voice Control homescreen (which is accessed by holding down the home button for a few seconds).In practice, the application performed admirably while making specific requests, whether it was dialing contacts, or playing a particular band.

Compass / Google Maps
In practice the inclusion of a hardware compass is actually really helpful when it comes to doing things like navigating a new city. As far as the hardware is concerned, the compass seems to do what's promised with pretty impressive accuracy.
