I have been releasing some iPhone SDK tutorials over the past week or so and I just released one on using SQLite databases.
It goes over how to create the actual database through to pulling the data out and displaying it. It is a simple example with a database of animals with their name, description and an image linked to them.
The actual app is a simple TableView which when you select a row (animal) it takes you to a view with their description and their picture.
I am also in the process of writing an addition to the tutorial to allow you to add/remove animals from the database.
