Wifi uses less battery than EDGE
I just read an interesting article about Apple's decision to go with EDGE rather than 3G. According to the analysis, 3G would have reduced the iPhone's talk time to less than 3 hours!
Another interesting part of the article was that "iPhone's EDGE implementation produced a 25% battery life reduction compared to its Wifi implementation." If I'm understanding this correctly, Wifi in the iPhone provides increased speed and better battery life! Good to know.
