HTC is now pushing out its first over-the-air update for unbranded European Sensations, according to reports from users in several European countries. The update package reportedly weighs just under 27MB, and brings the Sensation up to software version 1.35.401.1 -- the exact same version which leaked last week in the form of an RUU (ROM update utility).
The general consensus seems to be that this is a small, incremental update consisting mostly of bug fixes and the like. The new software is still based on Android 2.3.3, and there's no sign that the bootloader has been unlocked in accordance with HTC's new bootloader policy. However, there are unconfirmed reports that the new software remedies some of the lag that users have been experiencing in the Sensation's homescreen launcher which, if true, would be very welcome indeed.
If you've got an unbranded European HTC Sensation, head over to 'Settings' -> 'About phone' -> 'Check for updates' to grab the new firmware, and report back to us in the comments if you notice any changes.
