The bulk of Samsung's pre-iPhone offerings for the U.S. market were bar-type phones, sliders and flip phones such as the BlackJack (center) and D900 (right). They came in the same familiar shapes being produced by most cell-phone manufacturers.
The F300 (left), which boasts two LCD screens -- one on each side -- was included by Samsung in its trial brief in a graphic purporting to demonstrate Samsung's early-stage touchscreen design. However, the 2006 phone has no true touchscreen capability, only the ability to scroll by swiping your finger along the edges of the sensor button.
Apple is asking for billions from Samsung, but the case is unlikely to reshape the smartphone landscape.
