Wes MacDermott has some interesting posts on this subject in his blog.

OpenGL ES 2.0 supports pixel light and normal maps

LIghtmapping is your friend … perhaps normal maps for objects with minimal screen coverage.

GLES 2.0 does indeed support majority of what you will find in a typical DirectX 9.x graphic card but that’s very misleading considering that SGX 535 is about 700 times slower than the card I have in my desktop machine (running at iPads resolution - 1024x768)

= = really I talking about unity 3d(iOS) not supported

but Thank you for grant me !

And we talk about unity too.

Unity 3 iOS supports normalmaps if you target ARMV7 and OpenGL ES 2.0

if you only target ARMV6 or disable OpenGL ES 2.0, there won’t be any normalmapping, also normalmaps won’t show up if you don’t have pixellights cause normalmaps only exist in relation to per pixel lighting
