Getting started in Core Data for iPhone?

Question

I want to implement Core Data into my iPhone app. So what is the best way to learn Core Data specifically for the iPhone? I have 4ish hours that i can devote to this today,

Answer 1

Make sure you don't stop after the first document - Core Data Turorial for iPhone OS is excellent but then I tried to change the model and everything crashed with fairly cryptic error messages. Getting Started with Core Data is the next place to go. Unless you read the sections on versioning the data model you will probably run into big problems as soon as you start to adapt the example code for your own use.
