Thanks for the update. I've about decided to return mine for service yet again as it is still under warranty. Nokia customer service again implicitly admitted that the FBUS/serial cables COULD be made available, but declined to do so: "Nokia does not currently offer FBUS cables for consumers. Therefore, if your Nokia N800 Interent Tablet is malfunctioning and you are unable to update the device's software, we recommend that a Nokia authorized technician evaluate your tablet for repair."
