iPhone does not have copy and paste. But if you jailbreak, this can be solved with Clippy. Check it out:
if you look at
http://thebigboss.org/why-jailbreak-iphone/ you can see screen shots, but im sure apple will add copy/paste eventually with firmware updates there is many things you will see apple add, like when you put your finger ont he screen and turn it around and move icons, in older firmware you used to not be able to do that..
so i am sure we will see lots of new features soon to the iphone
