This is just the release of the firmware update for existing owners of the PRS-505 that allows the PRS-505 to support Adobe Digital Editions 1.5. Updated PRS-505 hardware devices with the update wont come out until next month.
If you have a PRS-505 and are having an issue with the new firmware or Adobe Digital Editions 1.5, you might be confused who to contact.
Essentially, if you seem to have an issue with the firmware update or the hardware itself, contact Sony. I believe the link is http://esupport.sony.com.
If you are having trouble with the content inside Adobe Digital Editions or with the PRS-505 bookshelf inside Digital Editions, open a Digital Editions 1.5 Technical Support case using the contact links at http://www.adobe.com/support/digitaleditions.
