I'd also like to ask whether a screen protector is necessary. If the screen is made of glass I would expect scratches to be a rarity. I've had it since the US release, and I'm not particularly easy on phones. But I haven't had any scratches yet (knock on wood!).
If you're in Edmonton, I'd recommend Ghost Shield. I'm not sure where else they are available, but Ghost Shield has worked great on my old 8900, and I'm just waiting til next weekend when they will have the Torch version available. Basically it's a coating they put onto your device, and it protects the entire phone from scratches, has a lifetime warranty, and this stuff is tough - you can take a screw driver to it and it won't scratch.
