Web connectivity

The iPhone is able to access the World Wide Web via a modified version of the Safari web browser when connected to a Wi-Fi or an EDGE network. It is not able to utilize AT&T's 3G or AT&T's HSDPA network in the U.S.. Steve Jobs has stated 3G would need to become more widespread 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, it will automatically switch from the EDGE network to any nearby previously approved Wi-Fi network.
Before the launch, some reviewers found the EDGE network "excruciatingly slow," with the iPhone taking as long as 100 seconds to download the Yahoo! home page for the first time. Immediately before the launch the observed speed of the network increased to almost 200 kbit/s. This is probably due to the new "Fine EDGE" upgrades AT&T had been making to their network prior to the launch.
The EDGE network benefits iPhone users by providing greater availability than 3G, as 3G continues its expansion to most major cities in the United States. Most countries outside the United States have very little EDGE infrastructure in place. For example, the United Kingdom's EDGE infrastructure amounts to less than 30 percent. As a result, many users outside major cities will have to browse the Internet on GPRS, a much slower protocol.
The web browser displays full web pages as opposed to simplified pages as on most non-smartphones. The iPhone does not support Flash or Java technology. Web pages may be viewed in portrait or landscape mode and supports automatic zooming by pinching together or spreading apart fingertips on the screen, or by double-tapping text or images.
Apple developed an iPhone application for accessing Google's maps service in map or satellite form, a list of search results, or directions between two locations, while providing optional real-time traffic information. During the product's announcement, Jobs demonstrated this feature by searching for nearby Starbucks locations and then placing a prank call to one with a single tap. Though Flash isn't supported in Safari on the iPhone, Apple also developed a separate application to view YouTube videos on the iPhone.
