iPhone Performance Question relating to CPU-WAITS-GPU

In the docs under measuring performance with the built in profiler it says that if the number for CPU-WAITS-GPU exceeds 2-3 ms then the application is most probably fillrate/GPU processing bound.

I'm desperately trying to increase the frame rate of my game and I think this may be the issue but I do not know for sure. I combined meshes on lots of objects in my game and this reduced my draw calls from 45 to 25ish. I'm currently running stats like this on average:

 iPhone Unity internal profiler stats:

Anyone have any suggestions for me to help my game's performance or possibly reduce the cpu-waits-gpu? The game is currently running choppy. I'm using an iPhone 4 for testing. Game runs perfectly smooth on the new iPad, but there is considerably more power in the new iPad.
