Amazon have released an update for the Amazon Kindle is said to increase battery life and provide the ability to read PDF documents as well as several other changes although it all depends which model you have to what new features and functions you get.
The new 2.3 Kindle update is designed for 2nd generation Kindles along with the Kindle DX. If you have a 1st generation device then you are stuck currently on version 1.2 of the software.
Kindle (Global Wireless) and Kindle (U.S. Wireless)
* Longer battery life for Kindle (Global Wireless): You can now read for up to 1 week on a single charge with wireless on. Turn wireless off and read for up to 2 weeks.
* Built-in PDF reader: Your Kindle can now display PDF documents without losing the formatting of the original file. Send PDF documents directly to your Kindle (via your @Kindle address) or drag and drop PDF files from your computer to your Kindle (when connected via USB). Learn more.
* Manual screen rotation: The Kindle screen can now manually rotate between portrait and landscape views so you can see the entire width of a web page or magnify the page of a PDF file. The page-turn buttons work the same in either orientation, and the 5-way controller movements are switched to match the orientation. Learn more.
* Option to convert PDF files to Kindle format. If you prefer to have your personal PDF documents converted to the Kindle format (so that they can reflow), type “Convert” in the subject of the e-mail when you submit your personal document to your @kindle.com address.
ll Kindles are designed to automatically check for and download updates when one is available. If an update is available, your Kindle will download and install the update the next time the wireless connection is activated and Kindle goes into sleep mode.
During the update, you’ll see screens that show the update progress. The update should take less than 10 minutes and is complete when Kindle displays the Home screen. Do not power off or reset your Kindle until the update is complete.
