Keeping Whispernet off is a pretty good way to avoid official updates... (Just sayin' ;p).

I'm pretty much of the same mind as yifanlu on the subject (that's why the enable_hack support is somewhat undocumented in my version).

I'm not really worried about hacked Kindles doing 'new' updates, once it's hacked, for all intents and purposes, we're in, we'll most likely always be able to alter the system one way or another, even without a jailbreak/a working otaup.
