BlackBerry 10 OS User's Guide

The BlackBerry 10 OS User's Guide is intended for all users of a BlackBerry 10 OS system, from system administrators to end users.

This guide tells you how to:

• Use the BlackBerry 10 OS runtime environment, regardless of the kind of computer it's running on (embedded system or desktop). Think of this guide as the companion how-to doc for the Utilities Reference. Assuming there's a BlackBerry 10 OS system prompt waiting for input, this guide is intended to help you learn how to interact with that prompt.
• Perform such traditional system administration topics as setting up user accounts, security, starting up a BlackBerry 10 OS machine, etc.

The BlackBerry 10 OS User's Guide is intended for programmers who develop BlackBerry 10 OS-based applications, as well as OEMs and other resellers of the OS, who may want to pass this guide on to their end users as a way to provide documentation for the OS component of their product.
