我有寫信去問過: The pricing of iPhone is still set at $0.99 USD primarily for historical reasons. It is our aim to move everyone to a single payment model that is priced at $1.99. We feel that if we charge on a yearly basis we will continue to do great things with our people and our technology to provide the best product and service we can offer.
As such, expect iPhone pricing to change in the future. 意思是說以後iphone的價格也不會那麼便宜了,可能會改成一樣的哦
