I use the little key (looks like a paperclip) that came with the iPhone to do it. Basically, all you have to do is put the end of the key (or paperclip) into the little hole and push firmly. The SIM door should pop out a little letting you pull it out with your fingers. Facebook: http://www.facebook.com/phonebuff.
