The iPhone has been noted by many for its high-resolution camera, even by legendary photographer Annie Leibovitz.

Leibovitz was interviewed by Brian Williams of MSNBC to promote her new photography book, Pilgrimage.

In an unaired clip, she named the iPhone as what she recommends when people ask her what kind of camera they should buy.

Calling the iPhone the "snapshot camera of today," she spoke of how the iPhone made tasks like sharing lives through photographs "accessible and easy."

"It's great, it's a pencil, it's a pen, it's a notebook. I can’t tell you how many times people show me their children. It's the wallet with the family pictures in it,” said Leibovitz.

Apple's latest generation phone, the iPhone 4S, released in October, is seeing immense retail success. The smartphone sold over 4 million handsets and continues to experience sell outs at a number of retail locations.

Wireless networks that carry the iPhone 4S, and others, noted that they have benefitted from the sale of the iPhone.

AT&T reported that it had impressive sales of not only the iPhone 4S but it also continues to sell the iPhone 4 and iPhone 3GS at record numbers.

Sprint recently acquired the iPhone with the release of the iPhone 4S, and reported that it broke records for best day of sale on Oct. 14 when the 4S released.

The iPhone 4S is especially noted for its high resolution, 8-megapixel camera.

Many suggest that the "S" in iPhone 4S stands for "shutter," referring to its camera.
