It's anyone's guess whether we'll see this mythical Supersonic from HTC show up at CTIA next week (wouldn't that be awesome?), but a phone identified as the HTC A9292 has recently made an appearance in yet another internal system which can't be a bad sign. As a refresher, the A9292 is popularly believed to be the Supersonic, a 4.3-inch Android-powered beast for Sprint that could become one of the carrier's very first WiMAX-enabled phones. This time around, the phone's turned up in a warehouse portal used by indirect third-party dealers, which would seem like a sign that they're getting ready to distribute these bad boys; hopefully we'll know all in just a few days' time out in Vegas. Stay tuned.
