Some things worth noting: Depth of field increases as the focus point moves deeper into the frame. Depth of field decreases as your lens length increases. Depth of field decreases as your sensor size increases. The A570 will have a relatively large sensor compared to a mobile phone, and your subject was very close to the lens. These things considered, the depth of field isn't impressively shallow. Reducing the sensor size to that of a phone and moving the subject further away will make shallow depth of field impossible. The portrait examples on that Google page are exactly the sort of thing that wouldn't have been possible previously.
