How can I check if a Kindle has been jailbroken?
Hi, I'm living in Shanghai, China, for some months and I'm thinking on buying a Kindle. Amazon doesn't send it to China, but they sell it everywhere here (they buy it in USA, take to China and resell in shops).
I believe that most of the Kindles that are in the shops, came jailbroken and with duokan installed, because it adds some cool features for reading Chinese characters, but if possible, I would prefer to buy a "clean" Kindle, with the factory default settings.
So my question is if there is any way to see in the menu if the Kindle has been jailbroken and has any kind of hacks installed (asking to the seller is not an option, they just answer what you want to hear).
