A couple of years ago, HTC launched the HTC Butterfly handset. The following year, there were rumors that HTC had planned a sequel called the HTC Butterfly 2 4G. The device has yet to be officially announced, although the closest thing to it being official was the fact that it was spotted on the AnTuTu benchmarks. Well the good news for those who are still doubting its existence is that the device in question has recently been spotted at the NCC, which is Taiwan’s equivalent of the FCC. The NCC filing has basically confirmed the name of the device, which is the HTC Butterfly 2 4G. It also seems to suggest that the launch of the handset might not be too far off, although we guess we’ll just have to wait and see for ourselves.
