Long story short, I grew tired of my bulky Otterbox and ordered an aluminum bumper from Amazon. I was a little hesitant after reading about the signal issues with metal cases.. I have ran several trials since receiving the bumper, and regardless of where I am in relation to a tower, the signal (dbm) is always lower (better) with the case on.. Have I found an anomaly, or is everything I've read about dbm's wrong?

The antennae in the GS3 are in the back of the phone, not the sides, so if the aluminum is only around the edges of the phone I wouldn't expect it to have much effect on the signal.
