After managing to crack my LCD screen in just one month I am wondering what's the best way to avoid this happenning again.

I have seen lots of cases for N900, but most are for protecting against droppings. My concern is about pressure cracking when in the pocket, sitting over it, etc...

Is there any case that would protect it against pressure on the screen? ie: one that have a thin but rigid sheet of metal inside, covering the front of the phone when closed.

I was expecting to break it sometime, but once in a month is just too much for me.... Perhaps I have been just unlucky? I don't even know exactly when it cracked, but I supposse it was while on the pocket.

.. And not carriying it in a pocket is not a solution, especially not during hot weather which is most of the year here.
