I spoke to optus last week about unlocking my old iphone to use in Bali. I was also told just do the update and it is unlocked. They also told me my brand new samsung is unlocked. They told me they don't need to lock your handset if you are on a contract anymore as you still need to pay out your 2yr contract if you want to leave your current plan/contract.
