Apple on Monday unveiled a new iPhone model called iPhone 3G S, which is faster, more powerful and has new capabilities like video recording and editing.
苹果公司(Apple Inc.)周一推出iPhone新机型iPhone 3G S。这款新机型速度更快，功能更强，并具备影像摄像及编辑等新功能。
The device immediately inspired lust among many consumers. But there are some calculations that people may want to make before snapping the new iPhone up.
这款设备立刻就引得众多消费者垂涎不已。但在出手抢购之前，人们或许还得精打细算一番。
For new AT&T customers, that calculation is pretty straightforward. Their price is $199 for the 16-gigabyte iPhone 3G S and $299 for the 32-gigabyte model with a two-year wireless service contract. (AT&T is the exclusive carrier for the iPhone in the U.S.)
对于美国电话电报公司(AT&T)的新客户来说，计算方法很简单。16G容量的iPhone 3G S价格为199美元，32G型号为299美元，均含两年期无线网络服务合约。（AT&T是iPhone在美国的独家运营商。）
But existing AT&T customers don't qualify for the introductory price, including those who bought the previous iPhone 3G model in the past year. Instead, the new iPhone would cost $200 more if they upgrade now.
但AT&T的现有客户不能享受这个起始价格，包括过去一年内购买了老款iPhone 3G机型的客户。相反，如果他们现在升级到新的iPhone 3G S，就需要再多付200美元。
Then there are those people who may just want the iPhone 3G S without a service contract from AT&T. For those consumers, the introductory price of the gadget would jump to $599 for the 16-gigabyte model and $699 for the 32-gigabyte model.
然后还有的人可能只想要iPhone 3G S手机，不想要AT&T的服务合约。对于这类客户，这款机型的起始价跃升至599美元（16G）和699美元（32G）。
