Sorry if these are redundant for some, but I've been reading and searching lately on the subject and trying to wrap my head around all the info I've found. I have some basic questions I'm not sure I've found definitive answers for: Is there an untethered jailbreak available for iPhone 4s on IOS 6? If not, can you download then downgrade to IOS 5.x first, then jailbreak, or would it be advisable to wait for a jailbreak for IOS 6 to be released? If the phone is factory unlocked (for GSM) will it remain so after jailbreak, or need another unlock? Are there other indicators or settings on the phone that you need to be aware of that would show that a particular phone is possibly un-jailbreakable (i.e. modem firmware, serial #, etc.)? RedSn0w or Absinthe, what is the difference, which is better/easier, why?
