If the above image is anything to believe, the HTC Sensation – either the European or the American version – is set to get a pretty sizable OTA upgrade sometime soon. The system verison looks to be 1.35.0.0 and the file clocks in at 369MB – yep, you’d better find a WiFi connection when you’re ready to pull this one down. We can’t even begin to imagine why an upgrade needs to be this large without a significant jump from one major Android version to the next. Anywho, the only hint we get here is that it’s “to improve the performance of your device and add new features”. [Android Central]
