There's also now the ability to reorder mailboxes on the top level of Mail, so if you have a specific, neurotic order that you like those in--I'm not speaking from experience or anything--then that'll be a plus. Also, for accounts which have both delete and archive options, you can tap the Delete (or Archive) button in a mail message, and you'll get a pop-up option for which action you want to take.

No doubt, some will be saddened that Apple has removed one configuration option: In the Mail, Contacts, Calendars pane of Settings, you can no longer set a minimum font size.

Finally, Apple's taken a page from the book of many third-party developers and implemented a pull-to-refresh mechanic for Mail, which replaces the old Refresh button that you could tap. Weirdly, Apple has done this in a way that's slightly different from how it's usually accomplished--pull down on the screen and you'll see a little blob that stretches out, as though you were pulling on Silly Putty. When the blob reaches the breaking point, it snaps back up and starts refreshing. The effect is vaguely unsettling, though I suppose it works all right. You can perform this maneuver on any of your inboxes, or from the unified inbox on Mail's top screen.

iOS's other marquee app is, of course, its Web browser. Like Mail, Safari's improvements are fairly modest in iOS 6, though there are a couple of additions that bring an extra dimension of functionality.
