In a press release, Amazon says the
"Battery power management for portable wireless devices is a complex technical area, and the battery life improvement announced today is the result of a six-month firmware improvement and testing program," the release notes.
As for the native PDF support, Amazon says you can now "read professional and personal documents in their original PDF format without conversion." To read PDF files, you either e-mail them to your Kindle e-mail address or move them over using a USB connection. If you prefer to have your PDF documents converted to the Kindle format, you type "Convert" in the subject of the e-mail when sending documents to your "@kindle.com" address.
All new Kindles will ship with the battery-life improvements and native PDF support in place, but if you bought an earlier Kindle you may be eligible for both enhancements via a firmware upgrade that will automatically download to your Kindle when you turn its wireless connection on.
We're still trying to determine which models will get the upgrade (we have an e-mail into Amazon's PR team). In the meantime, if you have an older Kindle 2 or the original Kindle, let us know if you got the upgrade.
Update 12:30 p.m. PST: We have confirmed with Amazon that the latest Kindle, released in October, as well as the Kindle with U.S. wireless (released in February) now have native PDF support and the improved battery life. However, as suspected, the original Kindle is not eligible for the upgrade.
