I have just checked this out, and many people are having exactly the same problem. Apparently you have to push the two grooves at the side of the phone in, and then push the cover in the direction of the arrow, however I know that there has been some trouble finding the grooves. If you are having a problem, it is probably best to take the phone back to where you brought it, and ask them to show you, otherwise type the question into google, as there are many help forums.
