Hi guys, thanks for that. I had my serial number noted down from my Amazon account and the police examined the Kindle and followed instructions as to how to go through Settings and then into Device information where the serial number is stored, so they had both numbers to compare. Have you by any chance, when you've opened up a Kindle, noticed a printed copy of the serial number inside the case that matches the serial number registered with Amazon?
Your comment about Airplane Mode is really interesting because it would have been in Airplane Mode when it was left on the plane, so that might explain why there were recommendations still there.
I haven't deregistered it yet because there were discussions with the seller online over the last few days, and I felt that if this was the Kindle in question the seller might have noticed that it could no longer be used, and would have removed the ad.
Im curious about root/shell access - would you be able to point me in the direction of more details on this? I'm particularly curious to find out if someone is wiping the Kindle clean (step 1 perhaps), is it then simply a case of step 2, change the serial number while I'm at it as it's easy enough to do? I'm guessing that if you change the number you'd need a viable serial number that you'd maybe
get off a broken device. Is access to root and shell through Jailbreak software? I only mention Jailbreak as I've been googling how to change the serial number and Jailbreak came up a lot when people were pimping up their devices.
Any comments gratefully received, and thanks for taking the time to reply earlier.
