($499 for 4 gigabytes, $599 for 8 GB; apple.com) With hip-hooray and ballyhoo, Apple CEO Steve Jobs previewed the much-anticipated iPhone at the Macworld convention. Combining a 3.5-inch widescreen iPod, a Wi-Fi-enabled "Internet communications device," and, oh yes, a cellphone, it also includes a 2-megapixel camera.
