I'm stoked about the new phone app. It's always bugged me that I can't divert calls and have to let them ring till it diverts to voicemail.
As unexciting as it is, Apple has also re-designed the phone app with iOS 6. One of the longest running functions in iOS it was getting fairly tired compared to a lot of the competition. So what now? Well incoming calls can now be dodged with an auto reply message via one swipe, as well as a swipe up to get a reminder about it later.
Do Not Disturb also looks cool:
A OS X Mountain Lion style "do not disturb" button will stop things like notifications lighting up the screen or making noises in the middle of the night. It is also possible to screen calls so people can be avoided. If someone keeps on calling however, you can tell the phone app to notify you.
