Does anyone know of a 240x320 calculator application that uses the directional pad (Dpad) to do operators like (-), (/) , (x), (+) ? Other phone companies have calculators which interface like this and i like it a lot more than having to scroll left and right to select these operators.

0-9 would remain numbers, Dpad left could be (+), dpad right could be (-), dpad up (x), dpad down (/). The asterisk could be decimal sign (.), # could be (%) and the left and right could be (=) or Clear.

Anyone know of a calc like this? Thanks all

EDIT: I have the W580i and W600i so I can only speak about the calculator programs that came with them.
