Will an aluminium case for my smart phone affect its reception ?

The aluminium case will block some of the radio waves.

I have a HTC Touch Dual phone. I am prone to dropping phones ,so the aluminium case would be great. I am just wondering if aluminium will prevent the radio waves from passing through and affect the performance of the phone...
