This is crazy. I just put my phone down on my laptop (on the speaker grille next to the power button) and it immediately went to sleep. Moving it and putting and putting it back again seems to wake it up. Does anyone have any idea why this is happening? I doubt it's a bad thing just really intriguing. I have tried it with a few mates phones and it doesn't work. Just my sony ericsson c510 with bluetooth on or off - doesn't matter. Madness.
