Cold can be applied in the form of a simple ice cube, or even canned air with the can held upside down so that only the freon shoots out.
Heat can be from a hair dryer or even one of those bean bag things that you microwave to apply to sore joints, (shoulder, knee, etc.)
Lastly, there is a product called Bestine that you should be able to find in many stores or online at places like Amazon. As with anything, be careful to avoid damaging the surface that you're trying to remove the sticky tack from.
