i jailbroke my iPad with jailbreakme.com. when 4.2 comes out what are my options for upgrading? -do i just accept the upgrade from apple and it happens automatically? -do i wipe it and restore a backup, then upgrade? -then once it's updated if i want to re-jailbreak, well, nevermind, i can look that up.... -does cydia offer their own upgrade to 4.2 in a few days/weeks so i don't have to re-jailbreak? -other? -what will i lose in any of the likely scenarios, what pitfalls should i expect and what can i do to prevent them. if these are clearly addressed in another thread, please redirect me or suggest a search, but i couldn't find it at first search in this forum.
