i found that the trick to is is to use your nail to open the bottom edge, it snaps open, and instead of pulling UP on it like you instinctively want to, hold the phone on its camera button edge with the screen FACING you
run your nail underneath the now top edge between the case and the phone, youll hear it snap off another clip near the right.
once thats top you push the cover to the right with the screen still facing you.
it doesnt come off like normal covers, it has to be kind of unlocked then slid sideways out. its weird to explain but it took me a few minutes and now I can get the cover off as easily as the triumph.
the REAL problem is that you have to do a battery pull to swap SD cards. annoying. haha
edit* basically the phone cover goes OFF in the same way it goes on, you hinge the top (power button side) portion first, and you hear it seal up and snap into the phone and the fingernail slot is the last bit to connect. its the same method off, dont yank it up.
