This is one of the most fascinating tweak for iPhone and iPod Touch which reminds you of good old school days when TV used to be of Cathode Ray Tube (CRT) technology. TV Tube Sleep turn your iPhone or iPod off in the same mode like old TV used to switch off by displaying white line and converging in center.
TV Tube Sleep does not have any icon nor any settings, its automatically applied and as you press the sleep button you will notice the CRT TV turnoff. Although we have covered lots of tweaks but this one fascinates a lot and remind you of old TV days. TV Tube Sleep is a paid application for 0.99 US$ however you can try it using the procedure here from xSellize repo.
