Iphone IR nightvision

I have been thinking of using my iphone 4 as an IR nightvision device. I have read that some of the Iphones have IR blockers built in.
Does anyone know if the Iphone 4 can see IR light, and if it cant is their a way to make it?

Thanks

They put filters on the digital cameras because it makes the colors wash out with out one.
They are all sensitive to IR though even with the filter, put a remote control in front of it and hit one of the buttons. you should see flashing light.
