but a faster network loads Web pages more quickly, true GPS functionality allows it to easily
find places nearby, and the new $199 price (down from $400) makes it an affordable luxury.
Before deciding whether to buy, however, make sure you can actually take advantage of
the iPhone 3G's high-speed data network. 3G stands for third-generation, which in non-geek
speak translates to Web pages and mail messages that, ideally, load about three times faster
than on the original iPhone. Even better, 3G coverage enables you to make a phone call and surf
the Web at the same time. That's great, if you live or work in a place where the 3G network of
AT&T (美国电话电报公司) (the sole wireless carrier of the iPhone) is active. That's not so
great in cities like New York where AT&T's cellular coverage is awful. As one of my colleagues
in New York City, who bought the original iPhone, commented, "It's just a toy. You can't make
phone calls on it, so I carry my Verizon phone with me all the time."
The real fun begins when you tap on the icon called "App Store" and start browsing the hundreds
of add-on applications that have been developed just for the iPhone. You'll find tons of games (I like
JirboBreak, a free game inspired by the Atari classic Breakout) and mobile versions of popular
websites like Pandora, Facebook, MySpace and the New York Times. Most apps will cost you,
but the vast majority are $9.99 or less. The apps work on the old iPhones too, but you'll enjoy them
a lot more on the iPhone 3G because many of the programs, including Yelp (local business reviews),
Whrrl (mobile social networking) and UrbanSpoon (restaurant reviews), use your exact location-
provided by the iPhone 3G's GPS chip-to make recommendations. The apps also load much faster
over the 3G network.

Advertising is a form of communication that uses all kinds of media, and is visible everywhere these days. Typical customers of advertising companies are other companies, or businessmen, who want to persuade potential customers to buy more of what they make or sell. But there are other kinds of customers. Some organizations spend large sums of money on advertising a political party or other group that sells what is not, strictly speaking, a product or service. Such non - profit organizations are not typical advertising customers, and they prefer ways of spreading knowledge, changing attitudes, and improving society. Many advertisements are designed to increase sales of products and services by either improving brand image or, in the case of non - profit organizations, expressing ideas. In order to achieve th~s, advertisements will often pass on truthful information while delivering their messages. Every major medium is a means of delivering these messages, including television, radio, cinema, magazines, newspapers, video games, the Internet and billboards (大幅广告牌). Advertising will usually be created and. placed by an advertising agency on behalf of company or other organization. Spending on advertising has increased greatly in recent years. In 2006, spending was estimated at $155 billion in the United States and $385 billion worldwide; the latter is expected to reach more than $500 billion by 2010. While advertising can be seen as a necessity for economic growth and social development, it is not without social costs. Advertisement emails and other forms of junk mail have become so popular that ~they have become a major burden to users of I nternet email services, as well as a financial burden on Internet email service providers.
