Jim Hamm reports: "I'm quite pleased with the speed of 3G on my iPhone. Zee and I just tried an experiment with our iPads. She has the new iPad with 4G here in Scottsdale. I've got the iPad 2 with 3 G. We entered websites in Safari and clicked send at the same time. Couldn't tell the difference. As the article explains only in certain conditions will one appreciate 4G speeds. For everyday surfing the net and emails, 4G probably won't make an appreciable difference."
