Calling all Macbook owners who have upgraded their RAM

Ok, im going to buy some RAM from Crucial (UK) next week for my late 08' MBP (upgrading to 4GB) and I would like to know what "size" screw drivers you guys used to unscrew the back casing. Sorry for sounding so anal Its just that I dont want to damage the screws. Im in the UK so I dont know if that makes any difference with regards to sizes/names.

Thanks as always everyone

Philips 0 should work fine.

used my handy philips on my pen knife for mine!

I got one of those kits with the tiny screwdrivers and those worked fine. I hear the small screwdriver you get with those eyeglass repair kits also work well.

Thanks for the info, im on the case
