It also automatically syncs all your contacts from a PC, Mac, or Internet service. And it lets you select and listen to voicemail messages in whatever order you want . just like email. The iPhone features the most revolutionary user interface since the mouse. It.s an entirely new interface based on a large multi-touch display and innovative new software that lets you control everything using only your fingers. So you can glide through albums with Cover Flow, flip through photos and email them with a touch, or zoom in and out on a section of a web page . all by simply using iPhone.s multi-touch display.
