your doing something wrong...0-)
seriously though.
you might be doing something like putting it in ur pocket or in a bag that is putting too much pressure on the bottom half of ur phone . my fiancee has gone through 5 moguls whereas ive had 1 mogul 1 TP. try storing it in a coat pocket or using the case and always think about how u store it from the time u get a new one.
it would seem that u have inadvertantly stored it in a way that will damage it .
just my 2 cents.
