Which cell phones can scan a UPC or ISBN?

I was told that the IPhone actually has a built in scanner to scan ISBN numbers on books and look up web information about the book, like how many currently on-line and prices. When I mentioned it to a friend, she said no.

So, I thought I would ask the collective if it is true the Iphone has the capability and what other phones do? I need to know before I make a decision on what my next phone will be.
