The iPhone's 2-megapixel camera lens sits at the top-left corner of the phone's rear face. Note that it doesn't look like there's a flash. And there's no self-portrait mirror either, unless the Apple icon can handle the job.
The iPhone's touch dialpad, as well as Talk and End keys, are only visible when you want to make a call. There's always a learning curve when working with a touchscreen; we'll soon see how steep the iPhone's learning curve will be.
