Pat & Steve, the pictures on the blog can give you some ideas using the camera in your phone. Many of the app developers are writing for the Droid platform now as well.
Larry, I have used an iPhone for years and I just started taking more pictures with it than ever before. You can get so creative and it's fun! I plan to write more blog posts about iPhoneography and apps or sites that are useful. It all started for me when a photographer answered the question "what's the best camera?" "The one you have with you, and we always have our phone."
Catherine, I took a look at your link. Looks good. But, alas, I have a Droid....
