All you need to know about Kindle firmware 2.3
Have you received your Kindle’s firmware update to version 2.3 yet? The update has been rolled out wirelessly for the second-generation Kindle and Kindle DX.
The main new feature is the ability for the second-gen Kindle to read PDF files natively, just like the larger DX reader. You can still convert PDF files to Amazon’s .aws format if you wish – and in some cases that’s the better way to go. Native PDFs are not zoomable on Kindle, so can be hard to read when smaller fonts and detailed diagrams are used.
The second-gen Kindle can now be flipped sideways to read documents with the player held horizontally. You activate the flip using menu controls – unlike the DX which flips automatically thanks to its internal accelerometer.
Another feature that has Kindle owners buzzing is greatly-improved battery life. Amazon indicates that the update dramatically improves battery performance. That translates to about a week of reading, with wireless turned on, from a single charge.
Our forum thread on the update is rich with tips on getting the update and reactions to the improvements.
To receive the update, you’ll have to turn wireless on (you knew that) and it may take some time for the update to find you. If you don’t have it by now, you may need to leave wireless on overnight.
There is also a procedure for manually installing the update, explained in the thread.
If you’ve installed the screensaver or font hacks, you’ll have to uninstall those hacks in order to receive the update. KindleBoards member NogDog has provided the hacks and some instructions on this webpage.
