Rules of the letter H

The letter H is not pronounced (it is silent) in Spanish, so it is very important to know the rules for the use of this letter.

In some foreign words, such as hadware or hamster, it is pronounced as a soft "J".
Also, in some regions of Spain and Latin America tend to pronounce the "H" in those words that in old Spanish were written with "F".
