An unlock method is looking pretty dismal as of now. I just got return labels for my 4 OOB 1.1.2 iPhones for a full refund and I suggest anyone else to do the same. Apple has extended their return policy for the holidays so even if it's been past 14 days you still have a shot.
Remember, if a software unlock becomes available, all you have to do is buy the iPhones again. No big deal.
