How do I turn off the HTC Desire boot jingle? Even with a set of headphones plugged in, when I reboot my HTC Desire it (ironically) still plays the 'quietly brilliant' boot screen jingle loudly on the built-in speaker.

This can be utterly annoying when lying in bed and the handset needs a reboot as it invariably wakes up the wife.

Can this be turned off or replaced?
There's an app for, well, turning off the sound on shutdown and then back on at startup.  As I've got Tasker I no longer use it, but you're looking for Silent Boot by Anton Weber.
