You don't say whether you have done the really simplest test of the shutter, 
which involves no film, no nothing.

take the film out.

take the lens off.

Take the bottom off.

Open the back.

Starting at 1 second, run through the shutter speeds while holding the body 
up to a white space -- the ceiling, the sky -- and look through the opening at 
each firing. In all cases you should see the shutter opening and closing, 
leaving brief (brief as the speeds decrease) image of a white square where the 
focal plane opens.

If the space, at the higher speeds, does now show this opening, then the 
shutter is not working properly. It could be simply an adjustment, or it could be 
that the pin/lever/whatever that retards the second shutter curtain is not 
doing its job and at higher speeds both curtains are slamming across there at the 
same time. At slow speeds where the slow speed gear is engaged you have a 
second mechanical system coming into play which could cause the shutter to work 
at slow speeds, but not fast. Sucks, but these things happen.

If that is the case -- and it sounds like it -- get it replaced/fixed under 
warrenty pronto.
