    The new iPhone 3G should please everyone. Its look and feel are only slightly improved,

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.
