There has been some dispute over the speed of the browsers on these next-gen phones. N95 users say that the 3G connection makes all the difference, iPhone users say EDGE is just fine when you’ve got a great app like Safari. As it turns out, they seem to go at about the same speed in their natural habitats, but when you throw a 3rd-party browser into the mix, it’s all over. Opera mashes them both; it seems that the “other” other browser is the king of the hill in the mobile arena. I can vouch for this as well – on my Helio Ocean, the built-in browser is better integrated with the UI, but for serious internet use, Opera’s the way to go.
