The IPhone - Can It Make Calls?

I think the IPhone is hot. So does everyone else. I have yet to read a post from any blogger talking about the basic functionality of this groundbreaking phone.Can this phone send a text message? Can I make a call and will it be crystal clear? If it can't do these two basic things properly then I don't want it.I mean that. I want to be able to do the basics incredibly easily with an almost 100% success rate before I know that I can teleport myself to planet Zookefrokenbakc and back with the IPhone.So I ask again, has anyone made a call or sent a text message using the IPhone?
