Understanding Kindle
Touch Firmware
At the core of your Kindle Touch is a small computer, complete
with hardware, software, and a built-in network platform. The
software that runs the Kindle Touch is its firmware. Firmware
is the core that controls how the device works — everything
the Kindle Touch does is controlled by the firmware.
Amazon periodically updates the firmware for the device.
Generally, firmware updates fix minor bugs and glitches that
may not be apparent to the casual user. However, occasionally
a major upgrade or new feature is added. For example, with
firmware update 2.5, Amazon added the ability to sort e-books
into collections, a feature that had been repeatedly requested
by users.
To find out which version of the firmware your Kindle is
running, from the Home screen, tap the Menu button, tap
Settings, and then tap Menu again. Tap Device Info from the
menu that appears. The firmware version is listed, along with
the serial number, and space available (in megabytes). The
Kindle Touch is the fifth generation of the devices that have
been produced, so the firmware version begins with 5.
