At first blush, the iPhone (left) and BlackBerry Bold (right) have similar setups for their apps and other functionalities: an array of icons that open tools and folders. These are visible as soon as you power on an iPhone; on the BlackBerry, your home screen (upper right) shows just a few key apps and your mail accounts' status. To see apps and folders, use the menu key to open a separate window (lower right). The iPhone's unified interface is easier to use.
