HTC Desire HD, Desire S to be updated to ICS as planned after all
"We remain committed to providing customers with the latest software updates when possible. As such, we are pleased to confirm we are still on schedule to deliver an Ice Cream Sandwich upgrade for both the HTC Desire HD and Desire S."
Originally, Canadian carrier Telus started the rumor by mentioning that the the Desire HD is performing poorly on ICS. It’s still not clear whether that particular carrier will have the device updated, but at least for all the rest, HTC has confirmed the upcoming availability of the update.
