Robo, I say get a cheap phone and wait till Rev. B. Personally, as I suspect it will be at least 12 months before there is an Australian release, I just bought a K800i to tide me over until the iPhone comes out... I have also skinned it to look like OS X
yea....that helps with the wait...
Is prepaid an option for you? You could perhaps go prepaid with a cheapie phone, then if you REALLY must have the iPhone on release, you can?
