At his keynote address, Steve Jobs revealed a slim phone-cum-MP3 player (he says it's thinner than the Samsung BlackJack) with only one physical control and a wide, 3.5-inch screen.

The Apple iPhone comes in 4GB and 8GB capacities--meager for a player with a design and resolution (320x480x160 pixels per inch) made for movies. But otherwise, the phone will play music and movies as well as any other iPod.

Running OS X and Safari, the iPhone will display Web pages in full. Reading them may be another challenge altogether.

iPhone will include a camera, of course. Two-megapixel shots will likely look nice on the broad screen.

Only time will tell whether the world likes to control a smart phone with their fingertips only.

An Apple-Google partnership paired with iPhone's Wi-Fi and and Cingular data networks puts maps on the iPhone.

Here, Steve Jobs shows off the phone's software-based number pad.

The iPhone looks surprisingly thin given its Swiss-Army mission.

The iPhone will run OS X, giving it plenty of room for new applications.

From the show floor, Jobs made the iPhone's first live call in public.
