Looks like HTC is going on something of an updating spree. According to reports from multiple HTC users, the Desire HD and Incredible S
have both received updates to Android 2.3.5 and HTC Sense 3.0, bringing
their software in line with more recent phones like the Sensation and EVO 3D. In addition, the Wildfire S
has apparently received an update of its own, and while it's still on
Sense 2.1, its Android version has been bumped up to 2.3.5, and it's now
sporting the fancy Sense 3.0 lockscreen that we've enjoyed on high-end HTC devices for some time.Source: XDA (1, 2, 3)
