There's no need to set any parameters in the default shaders. Their purpose is to mimic GL 1.x behaviour automatically. I'm unsure why this doesn't happen here though.
Here's a test case that I've hacked together that show specular lighting on a sphere in ES 2.0. Maybe you can run that on your device with and without specular lighting enabled and report the results.

Edit: I assume that you are using the latest version of jPCT-AE?
