At the iPhone event in Cupertino, CA, Apple CEO Steve Jobs outlined the application development process to the press and developers. It seems the applications will be delivered through an Application store icon directly on the phone or on a user's computer.

Several programs were demoed, including AOL Instant Messenger and games like Spore! and Supermonkey Ball. Applications that are free to the customer will also be free to distribute for the developers.

There are three new technology features in the iPhone that makes a biggest difference in the kinds of applications people can build:

-Using the iPhone’s 3D accelerometers, the iPhone can sense its own orientation to the earth in 3 axis and measure how fast and in what direction the iPhone is moved. With orientation and motion detection, users will be able interact with the device by holding or moving the iPhone in a certain way. For example, when using the iPhone’s phone function, dialing and holding the phone up to one’s ear disables the touchscreen, so that the user’s cheek doesn’t accidently interact with the screen. When the user moves the phone away from his ear, the screen is again enabled.

-Even without a built-in GPS, the iPhone can approximate its geographic position by using radio waves to measure its distance to surrounding cell towers. This position reporting is accurate to within a few hundred yards, and is much less accurate then GPS, which is accurate to a dozens of feet. Using the location services, applications can change their behavior depending on where in the world they are.

- This technology lets Bonjour-enabled devices interact with other Bonjour-enabled devices in the immediate area without requiring a central server. Now, two iPhones can communicate with each other directly, so long as they were within WiFi range.
