When the temperature of water is lowered past its freezing point, it turns to ice. The freezing point of water is cold to our touch, so it feels cold. However, other substances have much higher freezing points. For example, Iron has a freezing point which is very hot to our touch, and any temperature lower than that, iron is "frozen". So the odd piece of iron sitting in our house doesn't feel particularly cold (though it does a little because of the heat conductivity of iron). But if you were to lower the temperature of that iron to the freezing point of water (where ice can form) the iron would feel cold too. Does this help or make you more confused? ;-)

To add to the answer above. It feels cold because you are exchanging energy. The ice takes in heat and your body gives it off. Therefore the ice is taking in your heat making your body interpret the ice as cold.

Because if it were warm it would be water.

Its Frozen.

Ice is absorbing heat from the surroundings, and thus is cold. When you touch it, it's taking heat out of your fingers.
