This is not a bad idea at all! I'll take it a step up. I'd gladly take auto-tinting of the windows when the car is off -- LCD, baby! Wooo! This way, the entire internal contents are hidden when the car is off. My only concern would be an ultra-reliable mechanism, as it would suck if an electronic error tinted the windows while driving!
SonyEricsson's official bootloader unlock site has gone live! http://unlockbootloader.sonyericsson.com/ They mention this, which is quite bold and quite welcome: A great step in the right direction! This means no more hacking to take control of your device. Xperia's stock just went up a few points in the Capt'n's market: the Super stock exchange (SEX).
Any more luck with this? Can anyone lend a hand?
