Searching for Apple iPhone Provisioning Assistant

I'm trying to get started with an iPhone project. The book I am working with (Sam's 24 H开发者_运维知识库ours) says to go to the Developer Portal, which will present the Development Provisioning Assistant, and then click on the Launch Assistant button. My screen does not look like the picture in the book, and I can't find a Provisioning Assistant anywhere!. Is my book out of date (Feb 2010)? Or am I blind? My book indicates that I should be able to do this with a free account, but perhaps I need a paid account?

The following link describes the requirements to get provitioning profiles.
