Packt Publishing kindly sent me a copy of the book and here is the result of my review:
The book is very well written specially for beginners to Mobile Web Development. However, the experienced mobile web developer will also find very useful chapters on SMS, MMS sending and Paypal. The IVR chapter it is also a value added. The book covers all the fundamental useful tools needed to develop mobile web sites and applications. It is important to remark the excellent approach showing the limitations of LCD development and introducing the necessity of content adaptation. Also the example chosen is simple but at the same time enlightening. The author has demonstrated that he has done an excellent research on open source tools and standards for mobile web development. The chapter on Mobile AJAX has been also a very good choice, as Mobile AJAX is the future.
The only disadvantage I see is that Java development is not covered. Also an specific chapter on MyMobileWeb, including programming examples, could have been very positive
In a few words, if you are a serious mobile web developer that needs to have a good understanding of the tools and possibilities of this technology, you should definitely buy the book
