GPU profiling is not supported by the graphics card driver

I am using Unity 3.5 and trying to profile the performance of an Android application. The CPU profiler works fine, but for the GPU I get this message:

GPU profiling is not supported by the
graphics card driver. Please update to
a newer version if available.

Does it mean a newer version of the graphics driver in my Android device? I don’t think there’s such an update…
Is there any other way to check what’s going on in the GPU?

You can't do GPU profiling with Unitys profiler on mobile, be it iOS or Android, it only works on the desktop you would need to use the XCode 4.x profiler or the one offered by the creators of gDebbuger
