I'm looking to implement Amazon Web S3 service in one of my iPhone apps, but I was wondering if anyone knows where I can find a tutorial or some example code of how to implement the SDK on the iPhone. I'll really appreciate your help.

The comments of this post "[How to use the AWS SDK for IOS?](https://stackoverflow.com/questions/7631634/how-to-use-the-aws-sdk-for-ios)" don't show the tutorial I'm looking for. 

I'm looking for an explanation of how things work between the device and S3 to know how to implement my solution.
