HTC Sensation Update

What's this? This image submitted anonymously via the Android Central app shows a nearly 369-megabyte test update for the HTC Pyramid (aka Sensation)? Veddy interesting. We've got no idea whether this is the T-Mobile USA version, or the European version, but the latter recently saw an RUU leak out with a similar version name.

Either way, looks like someone's getting set to push out a sizable update.
