Ever since bling became more important to sell phones than sturdiness, this has been the risk people must live with.
Old style phones have a ledge, and much lower risk of having this kind of damage. But they also look ugly.

BTW does it still work ok? Sure sucks; good thing I got a flip cover from Ebay (hey, it's only about 2USD and 2 weeks waiting from China), that reduces the risk of such things happening...
