The title of this book is a blatant lie.NOWHERE in this book does it cover WAP 2.0.In appendix A, it clearly states the book is only about 1.1!It covers the 1.1 version, which is now out of date.Chris Tull is not to blame - he covered 1.1 wonderfully;it's the publishers who were afraid of losing $$ that need to be very ashamed. Black eye for Que on this one!Don't be fooled by the 4 star rating; 4 of 6 are duplicates!
