Chip-quick ( 
http://www.chipquikinc.com/newsletters/cq_new_june_2004.htm ) is great 
for doing SMT rework. It's a low melting temperature alloy, which you 
use like solder. It mixes with the existing solder to make device 
removal easy. It doesn't take much.

Although I am a big fan of ChipQuik you should try it on an old PC board
before you try it on something that might break your heart if you fail.
ChipQuik can send a part flying (along with a trail of molten ChipQuik) if
the part has been tacked down with an adhesive and requires a little
pressure. Once you get the hang of it, on a multipin IC, it can be a life
saver. I don't think I would use it on a resistor or cap though. I would go
with the single iron back and forth or the two iron method.
