iPhone SDK: How to get 4.0 on a device?

This is a question about installing 4.0 on an 3rd gen iPod Touch. I already have a developer account. I have also downloaded the 4.0 SDK with XCode. I can test the new functionality in the simulator but I want to also try it on my device hence my question. I am looking for instructions on how to get it on my new third gen iPod Touch. Could someone suggest a link that has worked well for them? than开发者_StackOverflowks.

In the iPhone portal there is a section entitled: iPhone OS Beta. There you can download the OS for the appropriate device. This appears once you accept the updated agreement, etc.
