Sony' sending out email notices that a firmware update is available for the Sony Reader Daily Edition PRS-950. That's the new model that just came out this fall with wireless, a touch screen and a Pearl E-Ink display. You can use WiFi on the reader to download the update, or install it via the Sony desktop software.
The firmware update allows the reader to sync your last read page-- they're getting ready for the smartphone apps that should be coming soon. You should be able to read on your Sony, then continue where you left off using your smartphone.
Reader Store notifications: Receive recommendations from the store that are delivered to your home screen.
Page Sync: sync last page read, bookmarks, highlights and text notes between Sony PRS-950 ebook readers (not sure how many folks need this, but that mobile phone syncing is sweet).
Capture screenshots: Take screenshots of a web page and handwriting viewer screens.
