I am not much aware of the rules, so I try to ask in meta before asking in main forum: Can I ask question about how to jailbreak Kindle?
Such a question would really be off-topic. It's not about ebooks; it's about a particular use of an ebook reader that is not about ebooks per se. In other words, it's really a question about the Kindle hardware and operating system. Any relation to ebooks themselves is secondary, at best.
I would vote to close a question about jailbreaking a reader, for the same reason I closed the question discussed in Should Kindle Fire questions not about reading ebooks be off-topic?
