I apologize for asking what would be basic information. As the title said, this is my first e-reader for, well, ever - I've build digital library for over a decade, and finally in good enough place to get e-reader.

Since I'm not on US or other place where Amazon ecosystem would be advantageous though, I decided I'll Jailbreak it. But, well, this is also my first time, so I have some questions.

1. Can I use it without Amazon account? After some search the result seems to be conflicting, but it might be a yes.
2. Can I just drop .mobi to it and read without Amazon account/nag screen? I want to test if the Kindle works without doing anything more.
3. Do I update it first then Jailbreak, or just go straight to Jailbreak? The second seems to make more sense, but I realize people might still want to be in Amazon ecosystem even when Jailbreaking (their books are there, after all) so maybe the first is actually common practice.
4. Is it possible to keep Kindle permanently offline/not connected to wifi? Since I'm not gonna be on Amazon ecosystem anyway, and I don't want it to accidentally update Jailbroken device... unless it's actually fine?
5. If I Jailbreak it and install ScreenSaver, does that means no ads? Amazon will deactivate the ad anyway since I'm not on US, as I understand it, but since I don't plan on logging-in, calling Amazon support might be trickier.
6. What do I do after Jailbreaking? Obviously, installing reader that support more format. I generally don't find dictionary especially useful, though. Beyond that, no clue.

Thanks for your time!
