Graphing Calculator  FREE app, designed to turn your cell phone into a Graphing Calculator.
It should work on all phones that support J2ME, like Nokia, Blackberry, Motorola, LG, Samsung, Sony Ericsson and more (specifically MIDP 2.0 and CLDC 1.1).
Current functionality:
 Up to three equations plotted simultaneously
 Three viewing modes (press enter/ok to switch mode):
 Zoom in/out up to 8* (press up/down)
 Pan up/down/left/right (press up/down/left/right)
 Trace any formulae, to help draw it on paper (press left/right to trace, up/down to switch formulae)
 Scientific Calculator funciton
 Supports the following;
 Binary operators: +, , *, /, ^(power) and parenthesis (, )
 Conditional operators: =, <>, <, >, <=, >=, and, or (for use in if statement)
 Arithmetic operators: sqrt, ln, log, exp, abs, ceil, floor
 Trig. operators: sin, cos, tan, csc, sec, cot, atan2
 Inverse Trig. operators: asin, acos, atan, acsc, asec, acot
 Constants: pi, e (eulers constant)
 Conditional logic: if(condition, then, else)
Example formulae:
 2*x^38*x+4 (remember to key 2*x not 2x)
 sin(x)*cos(x^2)
 if (x<2, sin(x), x^2)
Possible future functionality:
 Intersection calculation
 Polar equations
 3D plotting
