As expected, iOS 6 was announced at the WWDC keynote. There are a lot of cool features coming to the iPhone with the new OS.
First up is Do Not Disturb, which tells your phone not to bother you with any push notifications or texts. You can choose not to receive any calls at all or specify which people you don't want to hear from.
The phone app also lets you reply to a missed call with an SMS, or add a reminder to call back. Also new is geotagging, which would be helpful to tip you to call someone when you leave a building or a place, or home.
