We did catch this during our liveblog
of the SDK talk on Thursday, but just in case you hadn't seen them yet, it seems both the iTunes WiFi store and the calculator
will be getting new icons in the iPhone's 2.0 patch. Of course, the App Store
will apparently have its own icon as well, and we would assume, at this point, that each app will be able to take its own place on the home screen.
But while the Calculator icon change is kind of a strange one (does this mean the Calc buttons will also be square?), the iTunes change definitely makes sense. That will be the place to download music, while the App Store will be the place to download everything else.
