This book simply rehashes Qualcomm's SDK docs and adds some sloppy example code and some absolutely incorrect statements about BREW. I know people who have contracted work to the author's BREW software company. The company described many technical limitations of BREW, which were later proved simply not true. The company's programmers simply did not understand BREW. This book continues in that tradition.You are better off sticking with Qualcomm's SDK docs, which are skimpy but more correct and concise than this book. If you really want a gentle intro to BREW, Ralph Barbagallo 's "Wireless Game Development in C/C++ With Brew" is OK, but you will still need Qualcomm's SDK docs.
