Even though I'm currently a Droid user, I'm totally jealous of the iPhone camera (it takes way better pictures than my Droid) and the Instagram app. And now, another reason to be jealous/another reason to buy an iPhone: Blurb is making Instragram books!
It looks like a fun, inexpensive way to get all those images off your phone without having to delete them. Or, you could make them into a pretty, graphic photo wall like this.
