Just saw the apple keynote of WWDC 2008. Steve Jobs talked about the new 3G iPhone and its superiority over the Edge network. The video about the speed comparison was interesting, Safari took 59 seconds to load nationalgeographics.com on Edge. Interestingly Opera browser on my Blackberry 8310 (Edge network) takes 25 seconds to load the same page!
The load time on 3G network for Safari was 21 seconds.
