Is it safe to just upgrade from a previous JB FW? I've never actually done that before. What would I lose? Would I be wasting a bunch of data as the unjailbroken FW would not read the cydia apps and so on?
Also what does unpatchable mean exactly? Can I upgrade to 4.2 once it's out without jailbreaking again or does it just mean the same exploit can be used with any firmware afterwards? I've been out of the loop for a while so forgive me for my 'noobiness'.
