ADB is bundled with Android SDK package that can be downloaded from Android SDK download page. This tool is usefull for communicating with Android phone such as install application, copy files from/to device and perform some linux shell commands.
How to Install

• Download and install Java SDK (Ex: jdk-6u20-windows-i586.exe)

How to Use

• Connect the phone to your pc/notebook usb port
