I recently ordered 2 different silcone skins for my pearl, one from the seido company and another through blackberry. I must admit that both work well but the blackberry skin seems to be the better of the two. It seems better made, it's softer and seems to hug onto the phone a little more snuggly.
I ordered the seido one in black and found that it collected lint like crazy while my orange blackberry version isn't as much of a lint magnet, which I atribute to it's better quality.
I have yet to purchase a screen protector though...that's next!
