Got the clear case for it. And made the antenna internal. You do this by removing the antenna, and the plastic on the antenna. Sand down the antenna mount on the case. Solder the antenna upside down inside the phone. There is just enough space above the EMI shielding of the PCB. Mount the casing, and use plastic filler and some sanding to fill the antenna hole. The signal did not even drop one bar. Looks especially good with clear case and internal flashing antenna ;)
