My friend's cell phone got wet and the "6" and "8" keys don't work, so now she can't call anyone with those digits in their number unless they happen to be in her saved contacts list.
But if her phone had Calculate & Call, she could create the number indirectly, using addition and subtraction on the cell phone's calculator, and when ready, dial the number now shown on the screen.-- phundug, Jan 22 2007 Bun for you...I am for anything that will allow me to keep using equipment beyond the time that most techies would say it is dead.-- Salted Nuts, Jan 22 2007 random, halfbakery
