The documentation for a new device from HTC has passed through the hands of the discerning FCC seeking approval. The device was filed under model code PC10100 and supports AWS 3G, which is the radio frequency known only to T-Mobile USA, accompanied by the ever-so-common 802.11n WiFi band. It’s most likely that this is the G2, (aka Vision) which is nearing its debut. If that happens to be the case, the HSPA+ support mentioned in the documentation is finalized, if it’s not the Vision, then this, "PC10100" just might be the mysterious, multi-core “Glacier.” [FCC via Engadget]
