SAN FRANCISCO (AP) - Apple CEO Steve Jobs is introducing a new line of iPods.

Jobs is unveiling a new iPod Nano without any buttons. It has a touch screen instead.

He also is introducing a new iPod Shuffle, the lowest-end music player in Apple's line. Like the past generation, it can speak the names of playlists and songs. But unlike the most recent of the tiny music players, it brings back the square shape and buttons of Apple's second-generation Shuffle.

Jobs also says iPhone users will be getting a software update that offers the ability to upload high-definition video over Wi-Fi. And when people take photos, the new software will save three slightly different copies that, when combined, make for a sharper image.

The new software will be available next week for free, initially for Apple Inc.'s iPhone and iPod Touch.
