MacNN has unearthed an Apple patent that shows the concept of aluminum unibody design, first displayed in the current MacBook line, applied to iPods and even -- potentially -- the iPhone.

Gizmodo has presented some concepts along these lines before, though we're still not sure how Apple would get around interfering with the 3G HSPA, and future 3.5G HSPA+ and 4G LTE and other radios inside a connected device (which is why they switched to plastic in the current gen iPhone to begin with).

Still, from a sheer design, build quality, and fit and finish perspective... drool.
