I'm very happy to announce that the jQuery Mobile book that I wrote with Andy Matthews has now been updated to the second edition. It covers jQuery Mobile 1.3.2 (we couldn't wait for 1.4, unfortunately) and includes new UI features like panels and responsive tables.
You can order the book from Packt right now here: Packt
Another option is via the Amazon link below. I get a small kickback when you do and a kitten smiles. Amazon is showing the book as being unavailable till the end of October, but it really should just be a few more days.
I am proud of this book as I think it really helps explain jQuery Mobile in a simple, easy to approach manner. I hope you like it too.
