HTC is rolling out Android 2.3.5 update for two of its smartphones in Europe. These smartphones are HTC Incredible S and Desire HD. Both the updates also upgrade the Sense UI to 3.0, which was first seen in HTC Sensation.
These updates are being rolled out over the air, so you will get a notification on your device in the coming days. If you have already got the update, do let us know about the experience so far in comments.
HTC Desire S has already received the same update two months back.
