I need to get a case and screen protector for my iPhone 2G (first generation, not 3G or 3GS). Will the Apple store still have this stuff for the 2G iPhone or is it all for the new 3G and 3GS?

I am getting an iphone in the next couple weeks because my plans up.. i just wannted to know what accessories does it come with and do you get any itunes credit or anything with it? thanks!

I know the old iphone doesnt. But someone told me the new iphone 3g s responds to fingernail touches rather than finger tips. Thank you.
