What is the difference in a iPhone and a iPhone 3g?

Answer:
There are several differences between the original iPhone and the 2nd generation, iPhone 3G! The biggest is that iPhone has switched from using EDGE, (which is similar to 3G, but not as fast!) To 3G. It is faster, thinner, lighter, and has many software updates too. The most recent update is the iPhone 4, and the iPhone 5 should be revealed on October 4th.
