GL_OES_texture_3d question

hi

I was programing with  the iphone 3GS , which need use 3D texture. I have searched  the web ,WWW.opengles.com,  and found the extension GL_OES_texture_3D.  

 

I would like to know  whether the  powerVR SGX support this extension?

3D textures are not supported on the iPhone 3GS. You can find a list of supported extensions in Apple’s documentation.
