HTC Sensation users in Europe are reporting that the long-awaited Android 2.3.4 update for the device is now being pushed out over the air. There's no changelog available from HTC just yet, but being Android 2.3.4, the update should add video calling capability through Google Talk and the front-facing camera. If we had to hazard a guess, we'd say that a sprinkling of bug fixes and performance improvements may have been sneaked in there too.
It's also worth mentioning that this update is for unbranded Sensations only for the moment, so if yours was bought through a carrier, you'll have to wait a little longer while they approve it.
Unbranded Sensation owners, be sure to hit the comments and let us know how your update went.
