here's a trick that works with images that are greyscale (they can be in a rgb or cmyk doc, they just can't have colors):
add 'new layer'
do command+option+~
(or control+alt+~ on windows)press the 'd' key
press option+delete
delete your original layer.
what was white is now transparent, gradients anti aliasing and all, in tact.
this also works if you only have a bitmap of a one-colored logo and you need to make it transparent. Only you need to desaturate it first (command+shift+u) and correct the black and white points (command+shift+l).
you can make the black/gray to be a tint of any color by selecting that color and hitting option+shift+backspace.
Oh, did i mention–Photoshop is my bitch.
