How about a case that's part metal and part plastic? Make it plastic just around the antennas (which, IIRC are at the 'ends' of the phone) and metal everywhere else? Heck, it could end up having a *good* effect by being extra shielding between the antennas and the (noisy) electronics of the phone itself.
