Fanboys and gals here get to buy iPhones in Sydney in under nine hours thanks to a midnight launch by Optus. Theirs is the pick of the three telcos for a value priced plan, according to this story.

As a happy customer with a 3G HSPDA plan (AUD$30 for 5Gb/mth incl. 'free' Huawei 3G modem), I am hoping to use that existing 3G SIM in a vodafone-locked iPhone - once the hype has died down.

Do you think it's possible and a good idea to get Vodafone to duplicate a SIM for me in order to have another SIM (using my existing 3G plan) for the iPhone?
