The other new option here is the capability to choose a different alert sound for each email account, as well as for VIP messages. Which means there are now three places you can choose sound alerts for new email messages:

For years, emailing an image or video you've taken on your phone has been counter-intuitive: you had to open the Photos app, choose the item(s) you want to send, and then create an email message, with those items attached, from within the Photos app.

Not anymore. In iOS 6, you can finally add photos and videos to email messages the way every other email client does it: from within an email message. However, the procedure isn't immediately obvious.

When composing a message, tap-hold or double-tap in an empty area of the message, and in the popover that appears, tap the right-facing arrow. Tap Insert Photo Or Video and a Photos-app-like media browser appears. Choose an album, and then tap any image or video in that album to view a preview. If you like what you see, tap Choose to add the image or video as an attachment. Repeat the process for each additional item you want to attach. (I've successfully added 12 images to a single message; I haven't yet discovered if there's a limit.)
