iOS unity profiler cpu waits gpu

I guys,

I'm wondering why am i not seeing cpu-waits-gpu and some of other statistics in the ios unity profiler:

 ----------------------------------------
 iPhone Unity internal profiler stats:
 cpu-player>    min:  9.2   max: 15.5   avg: 12.3
 cpu-ogles-drv> min:  1.2   max:  2.7   avg:  1.6
 frametime>     min: 12.9   max: 20.1   avg: 16.5

 mono-memory>   used heap: 610304 allocated heap: 872448  max number of collections: 0 collection total duration:  0.0
 ----------------------------------------

Maybe i need to enable something else? When i enable ENABLE_BLOCK_ON_GPU_PROFILER, i see GPU>..Is that the same as cpu-waits-gpu?

Thanks in advance :)

EDIT: I'm using Unity 3.5, Xcode 4.6.2, and doing test on an Iphone 4 xD
