Thanks for your quick help. I am still stuck. Here is a walkthrough of what occurs:
(0) With the iTunes application open on the laptop, when I click its File drop-down menu, I see a Get Info (Ctrl-I) line, but it is grayed out.
(1) With the iPhone turned on, I connect it to the laptop. In the laptop-resident iTunes application I see the iPhone's entry appear under DEVICES. The entry shows a battery image and an Eject gadget.
(2) I select the entry. Now I see a tempting ad for MobileMe appear in the main frame. I do not see an Info tab. When I again click the File drop-down menu, I again see the grayed-out Get Info line.
