Quick question, because I am really somewhat new to Jailbreaking if it comes down to it: I am currently still running the 5.2.0 version of the Paperwhite operating system -- if I jailbreak it (which is essentially just adding a developer key to the keystore?) and then update to 5.3.0 the jailbreak will be essentially gone. That's what the "bridge" is for -- could you elaborate on how that works and if I can completely revert any changes made to the Kindle?
I am a bit scared of jailbreaking my device and then suddenly receiving an update which leaves my Kindle in a half-broken/half-working state because I messed with some system files. Basically I want to know: What do I do after jailbreaking my 5.2.0 Kindle Paperwhite? Can I create a full backup of some kind and later revert to it? After installing the Jailbreak "bridge" and updating to 5.3.0 will I still be able to remove the Jailbreak/installed hacks if I choose to do so?
