If you believe the hype from Apple, the iPhone 4 changes everything again. (Does it?) Here is Apple's latest video showing off the iPhone 4.
In case you missed it, Steve Jobs had his iPhone 4 keynote address today and WWDC. Jobs announced the new iPhone, with new features like iMovie, Face Time, and iAds. The iPhone is thinner, has a front facing camera, better display, and is all around much better than previous iPhone models. But, does it change everything? Maybe, but maybe that's just Apple's marketing hype.
The iPhone 4 is definitely a step forward but I think the iPad "changed everything," but the iPhone 4 is just another step forward for iPhone.
