Optus has officially announced their iPhone prices. And it's cheap - only $228 for the iPhone paid over 12 months.
If you opt for an unlocked phone, it's going to cost you quite a bit more - $736 for the iPhone 8GB. This means you're far better off committing to a 12 month contract, even if you never use the phone during that period - you've saved over $500!
Unfortunately I'll be at World Youth Day when the iPhone is released - anyone want to buy me one?
