Bug in Spherical Plot 3D, Mathematica version 7
Posted:

The following should yield a hemisphere:  2 Pi/5 \le \[Phi] \le 3 Pi/ 5.
SphericalPlot3D[UnitStep[{Sin[\[Phi]] Sin[\[Theta]], Cos[\[Phi]] Sin[\ [Theta]], Cos[\[Theta]]}.{Cos[2 Pi/5], Sin[2 Pi/5], 0}], {\[Phi], 0, 2 Pi}, {\[Theta], 0, Pi}]
What I get, on my Mac, OS 10.7.4, looks like a helmet. I could send you a copy of the plot by email.
I have low expectations for Mathematica, but they just bottomed out.
