Last week, we released the "Practical symfony" paper book (380 pages). The "Practical symfony" book is based on the Jobeet tutorial, and is the best book to read to get you started on symfony 1.2. It describes everything you need to know to develop professional web applications with the symfony framework.
As for the Propel edition, we have worked hard to update the Doctrine edition as fast as possible. The Doctrine version is now up to date and thanks to Jon work, you can even enjoy a tagged repository for each day of the tutorial.
The book works through the Jobeet tutorial series they posted at the end of 2008 to create a complete job posting website with the symfony framework.
