Limited numbers of HTC Sensation and Sensation XE owners in Europe have been receiving over-the-air (OTA) updates to Android 4.0.3 Ice Cream Sandwich and Sense 3.6. HTC had eluded in a previous statement that the Sensation and Sensation XE would be getting an early taste of Ice Cream Sandwich in Europe with entire line (including the Sensation 4G and Sensation XL) to be updated by end of March.
The update comes as a hefty 200MB+ download and seems to be rolling out to individual countries in stages and specifically to unlocked (i.e. without carrier branding) handsets. If you have an unlocked European handset and are anxious for the update, you can download the leaked HTC RUU 3.30.401.101 and 3.30.401.1 on a Windows computer to manually update either handset.
