A couple of notes for iPhone users. The first is that Web pages you add to your home screen do not automatically update their icons when the creator of a site changes them. I noticed that Google Reader had a new favicon this morning, and guessed that they’d added an iPhone WebClip icon as well. I opened Google Reader to see if the WebClip icon changed automatically — it did not. However, when I deleted the WebClip bookmark and added it again, Google Reader did in fact have a custom icon.
The second note is that Google Reader has a new WebClip icon, so go get it. Google Mail and Google Calendar still don’t have their own icons.
