I decided to order some Kapton tape after reading the Anandtech article to shield the antenna from interference. I have tried multiple cases and even the bumper but i just hate adding any bulk to this device. I already have an SGP leather skin guard on the back and an SGP crystal on the front. I had had a precut decal around the phone but it didnt really do much for shielding the antenna. I took off the decal (which was precut) and laid it ontop of a strip of Kapton tape. Then i took a razor blade and made the cut outs on the tape tracing the cutouts on the decal. This was very very hard to do well but i think i got close enough. After measuring with speedtest multiple times I can say that the tape is magical. Performs equally as well as if I had a case on the phone. Also am loving the amber/gold look. Some Pics attached. Sorry they are not the best but am at work. Will update with some higher res ones tonight.
