Internet connectivity
Internet access is available when the iPhone is connected to a local area Wi-Fi or a wide area EDGE network. The iPhone is not able to use AT&T's 3G or AT&T's HSDPA network. Steve Jobs has stated 3G would need to become more widespread in the United States and much more energy efficient before it's included in the iPhone. By default, the iPhone will ask to join newly discovered Wi-Fi networks and prompt for the password when required, while also supporting manually joining closed Wi-Fi networks. When Wi-Fi is active, the iPhone will automatically switch from the EDGE network to any nearby previously approved Wi-Fi network.

The EDGE network benefits iPhone users in the U.S. by providing greater availability than 3G, as carriers based in the U.S. do not have full 3G coverage. By contrast, 3G coverage ranges from 60 to 90-percent in the United Kingdom.

Since the iPhone's inception, the use of the handset for Internet connectivity has exposed one or more trends. According to AT&T and Google, the iPhone generated 50 times more search requests than any other mobile handset. The iPhone also increased the average wireless data usage as much as 30 times higher than on other phones, or 100 MB per iPhone customer. iphoneinfo click here
