pvr is present and can be used, its independent of the OGL ES version and iTGB does not support OpenGL ES 2.0 at all its always only OGL ES 1.1

What I found in the end is that i didn't need it and the game ran fine with PNGs.

Edoardo, before you go down the PVR route, I haven't been impressed with PVR on the iPad - the higher res seems to stress out the artifacts a lot more - less noticeable on low res 480x320 and smaller screen.What I found in the end is that i didn't need it and the game ran fine with PNGs.

Results will always be terrible on any large gradients, but "busy" little sprites are normally fine.

Compression artifacts is expected with all lossy compression methods ;)Results will always be terrible on any large gradients, but "busy" little sprites are normally fine.
