I hope some developers can brief us with unannounced features. So far Apple only paid attention to the major changes.

I'm curious about the quicklook feature for previewing documents.
I thought the iphone OS had no centralized document storage area, so where are you going to see a list of documents that you can then quicklook at??

Or until they can jb it.
Anyway, I want ABC and networks/TV apps for th iPhone. Hope they don't hold bac just to get you to buy an ipad?
Also. My iPhone is the 3G 1.5 years old. How can I tell what bootrim I have? This is important if you want to upgrade to 3.1.3. Would like a 3GS but if it can't be jb, unlocked, why bother. To many great non apple storecapps out there. Peace.
