How are we going to type text into form fields on web pages using iPhone's "mini-Safari"? All we've seen Steve do so far is type into the address bar and search bar. Those would bring up the half-screen keyboard on the bottom.
But what about typing in, for instance, search fields? Do you think the keyboard will pop up when you click in a text field? Or will it be enabled some other way?
Also, do you think it will be possible to upload files from iPhone? If I take a picture with my iPhone and I go to Flickr.com, will I be able to hit "Upload" and browse over to /Pictures on iPhone? What if I saved a file from a webpage? I guess the bigger question is, what does iPhone's "Home folder" look like?
I know we'll lose a lot of browser features as a consequence of the size, but these sound crucial to me... Ideas?
