First, let me add my voice to those of other Kindle owners who like the "disable updates" feature... There are more than two or three of us who want to prevent Amazon from modifying our Kindles whenever Amazon chooses (without having to turn off our Kindle's wireless connectivity forever).

We don't necessarily need to disable updates, as long as we can disable auto-updates.

We don't need the autoupdate-disabling hack to be bundled with a jailbreak hack. Ideally it should be an independent hack all by itself. For the same reason that it shouldn't be bundled with a jailbreak, it shouldn't be bundled with any other hack.

Also, I (and others too, clearly) want to be able to save a copy of our Kindle's firmware to a file on our pc, and later restore it from pc back to Kindle. This would allow us to experiment with Amazon updates and 3rd party hacks and then rollback if not satisfied. (If this can already be done using existing hacks; then all that's needed are clear instructions: which hacks are required, and the procedures for saving & restoring the Kindle's firmware.)

Of course, the ability to restore the older firmware must be robust so that an Amazon update (or malicious 3rd party hack) can't modify the Kindle in a way that blocks the restoring process. I don't have the expertise to suggest how that might be done, but I'm wondering if a "sandbox" hack could be created, so that Amazon updates and 3rd party hacks could be installed without risk that they can't be uninstalled and their effects undone?

If users can be confident they can rollback their Kindles, they won't need to disable updates.

Another value of a sandbox hack would be to block trojan functionality that might be embedded in some other seemingly innocent hack (screensaver, fonts, whatever). For example, I wouldn't want a trojan to be able to turn on my Kindle's wireless in the middle of the night and upload information to a hacker.

Thanks for considering this, and best wishes!
