In iOS 5, when you tap to share a photo, you get a long list of sharing actions to choose from--whether it's posting to Twitter, sending an email or iMessage, or some other option. iOS 6 adds Facebook sharing as an option, along with sharing to various Chinese social networks. (That's a nod to .) But Apple decided against cramming more buttons into that panel.
Instead, iOS 6 presents you with a new, icon-based sharing screen. It uses icons to represent the apps and services that you can share your content with and looks quite a bit like the iPhone's home screen.
Flagship include the voice-driven personal assistant's arrival on the third-generation iPad. Siri also gains the ability to answer questions about sports and movies in iOS 6, and it will be integrated with turn-by-turn directions in Maps. But the virtual assistant gains several other new features as well that might have escaped your attention.
