As a developer , I get an advanced look at the Operating System in the new iphone, it is known as IOS6. It is interesting that they are incorporating Nunchi type features :

" iOS 6 allows you to answer or decline phone calls with preset or custom text messages, or to set a reminder to respond to a declined call. It also includes the option to configure do-not-disturb times. Call avoidance is about to get much easier."

This from a develper blog. I remember e.digital mentioning this feature in Nunchi.

Also, Siri is getting more useful, "The new, improved Siri can make reservations through OpenTable, post tweets, and launch specific apps"
