HTC Myst approved by the FCC with AT&T-compatible LTE

HTC's next "Facebook Phone" has been in the rumor mill for much too long, but this morning's approval by the FCC may speed along its journey to a launch date. The PM33100, which has been long associated with the Myst (or Opera, going even further back in time), just received the go-ahead by the Feds -- and it's carrying the same four LTE frequencies that we normally see accompanying AT&T smartphones. Naturally, HTC is keeping as much to itself as it possibly can, as we were able to glean few other details from the documents, but we know it has dual-band WiFi and Bluetooth 4.0. However, if the leaked specs provided by @evleaks are correct, we should also expect to see it come with a 4.3-inch 720p display, a 1.5GHz dual-core MSM8960, a 5MP rear camera and Android 4.1.2.
