Mobile Guide to BlackBerry

When I started writing this book, the 7100 series handhelds were not yet released. As a result, the 7200 series handhelds were chosen as the newest yet most representative of the handheld models available. For this reason, the majority of the figures show a 7200 handheld.

This book then is based on the 3.7 version of the handheld software. 3.7 is the version most color handhelds use and is not significantly different than the previous version, 3.6, which most of the monochrome handhelds used.

During the writing of this book, the 7100 series handhelds came out with version 4.0 of the handheld software. Version 4.0 introduces some new features as well as adds support for the new 7100 series handhelds. These new features are covered in sections that specifically indicate that they are part of the new version 4.0 handheld software. In addition, the 7100 series handhelds behave a little differently than the other handheld models available in some areas. These differences are often noted in special notes. When something works in a different way on a model 7100 handheld, I say so.
