In Apple’s SDK announcement on Thursday, it was revealed that all iPhone users have a brand-new 2.0 update to look forward to in June.
Steve Jobs finished the program by saying that they would be talking more about it in the coming months, but some clues have been left to suggest features beyond what was specifically announced (Exchange support and other enterprise features, the App Store, etc.).
First of all, Apple itself mentions that Mail (”Mail Touch”?) will include:
the ability to view PowerPoint attachments, in addition to Word and Excel, as well as the ability to mass delete and move email messages.
Blog blargKABOOM points out that sharp-eyed viewers of the event video may note the presence of a new magnifying glass icon on the contacts list in the Phone app. Search is finally coming to the contacts list! (This makes sense, given that the new enterprise/Exchange features open up potentially tens of thousands of contacts, which would make scrolling a chore.)
The presence of a new & improved Calculator icon also caught my eye:

Perhaps this means we’ll finally see a more full-featured calculator, rather than just the free-from-the-bank pocket calculator?
I’ll keep my fingers crossed, but I do recall that the last time the calculator icon was changed, we got no such new features.
Additionally, of course, there are minor cosmetic changes to see in the video, such as the new iTunes WiFi Music Store icon (at right), which is presumably shedding its download arrow in favor of an iTunes style musical note to help eliminate confusion with the new App Store, which offers downloads of a very different sort.
And, of course, Calendar reflects changes to help facilitate the new Exchange features, moving the buttons to the bottom of the screen and adding an Inbox icon for meeting invitations, etc.
But, perhaps most exciting to see in the event video is Bob Borchers, senior director of iPhone product marketing, outside of that dark iPhone tour room that made him famous:
It’s nice to see the iPhone family out and about! :) And check out that stylish new MacBook Air, too…
