Hi, I would like to turn off my HTC Desire's screen but to let it work as if screen was on (i.e. WiFi, etc.). There are plenty situations where it might be interesting to do this: You're downloading huge files, and you want to economize battery a little bit; You're using GPS-tracking programs (such as those you find for monitoring your favourite sport) which evidently need GPS to be turned on, CPU to work fully, but which do not need the screen to be turned on (and you won't look at it, mostly). I looked everywhere, but I can't find a way to achieve this. I simply want screen to be turned off, but everything to work as if it was turned on (except screen's reactions, evidently). It should also, if possible, prevent the device from going into sleep mode (except if the battery is very low, evidently). If this is not possible, I'll look for another program to do this, but I'm mainly looking for a program to turn this screen off. Any idea? Thanks.
