The iPhone 4 is no small thing to review. As most readers of Engadget are well aware, in the gadget world a new piece of Apple hardware is a major event, preceded by rumors, speculation, an over-the-top announcement, and finally days, weeks, or months of anticipation from an ever-widening fan base. The iPhone 4 is certainly no exception -- in fact, it may be Apple's most successful launch yet, despite some bumps on the road. We've already seen Apple and AT&T's servers overloaded on the first day of pre-orders, the ship date for the next set of phones pushed back due to high demand, and die-hard fans in line outside of Apple locations a week before the phone is actually available. It's a lot to live up to, and the iPhone 4 is doing its best -- with features like a super-fast A4 CPU, a new front-facing camera and five megapixel shooter on the back, a completely new industrial design, and that outrageous Retina Display, no one would argue that Apple has been asleep at the wheel. So the question turns to whether or not the iPhone 4 can live up to the intense hype. Can it deliver on the promises Steve Jobs made at WWDC, and can it cement Apple's position in the marketplace in the face of mounting competition from the likes of Google and Microsoft? We have the answers to those questions -- and many more -- in our full review, so read on to find out!
