The “Fourth-Row” itself should be designed at 120 pixels tall and 640 pixels wide, and will get resized to 60 pixels tall and 320 pixels wide when displayed on older iPhones (3G, 3GS). The entire content area (include the fourth-row) should be design at 472 pixels tall and 640 pixels wide, and will get resized to 236 pixels tall and 320 pixels wide when displayed on older iPhones (3G, 3GS). The bottom toolbar will cover the bottom 88 pixels of the design (44 pixels on older devices) and is slightly translucent. All of these values are much easier to understand and work with if you will use the above linked file.
