I realize that this thread is very very old, but I am digging like crazy for this information. I have found 3 ROMs that don't light up the backlight when the joystick is moved / wiggled / touched.
1 One is the Cingular 220.127.116.11 ROM
2 One is the T-Mobile SDA original ROM
3 The other is a baked ROM from XDA-Developers that is an iPhone look alike.
I can't find where to download ROMs 1 & 2 above. Rom 3 is great, but I haven't been able to synch with my work Exchange server with this phone since the flash, something with the registry and the push of the certificate / policy from the Exchange server requiring a simple pin an device lock.
For reference, the iPhone rom is in a thread here -> http://forum.xda-developers.com/showthread...highlight=vista
