tardtasticx: If its like the past ones I assume it'll be available launch day. Went to the iPhone 5 launch at the Victoria St store in Auckland CBD, was an interesting experience.
Thinking of buying from Apple directly this year as not too keen on signing a contract. But if Spark offers it on prepaid/pay monthly right away I'll switch to pay monthly and stay with them most likely.
We will offer 12 or 24 month interest free. I think that also applies if on Smart OneBill, I'll need to check that (as smart one bill is on the account)
