Actually I popped my out the first time I tried to put the sd card in the pearl.
With a lot of patience i managed to reseat it. Its a very much trial and error situation but eventually it just pops in. Unless you have bent it. there are very subtle grooves that it sits in. With decent eyesighrt or a magnifying glass you should be able to get it to sit comfortably. I had to use the magnifying glass.
