I have a question regarding the jailbreak survival code.
On the wiki I read:
"This is the ONLY TIME you should ever use the Reset menu entry in the lifetime of the device because it wipes out the jail break survival code that is about to be added in step 6 below. NEVER AGAIN USE THE "Reset" MENU ENTRY. "
Why would there be no way to install again this survival code in the future if needs be? Couldn't a kindle be jailbroken / reset / jailbroken again?
Thanks for clarification (and the great sharing of knowledge in all those interesting posts!

)
