Hi! Just registered

I could provide this, but I'm doubtful: firmware 3.2.1 seems to break current jailbreaking, and while I'm still on 3.2, when and if amazon rolls out the update to my device I'd be pretty screwed as I could not remove any hack anymore. Is my fear not something to worry about or should I wait for a proper jailbreak for 3.2.1? Also, are firmware updates automatic? When do they happen? Thanks
