4S Antenna replacement

[1zach4]

I have seen people with polished antenna bands on the iPhone 4, and I have also seen a black anodized antenna assembly for the GSM version of the 4.

Does anyone know of a place to get different antennas for the 4S?

I'd really like a black anodized antenna assembly or possibly some sort of flat black

The antennas are highly integrated into the body of the iPhone 4. It very likely that they where either polished, a custom job, or a skin of some kind.
