Has anyone had any luck finding the official LG Wireless Charging Quick Circle case? Sprint stores just carry the snap on circle case. I've been to At and T and they have one, but it's for Powermat, not QI charging (apparently they use that as a standard across all their phones). Verizon has it at a store across town, but I'm afraid it's going to have the logo splashed all over the back and be a wasted trip. Thanks in advance.
