The iPhone 4 has already been amazed the world with its radically redesigned look, which Gizmodo revealed early after getting its hands on a prototype.There is no question about the fact that iPhone 4 is more smarter, more reliable and easy to operate capability.
A 3.5-inch Retina Display put pretty much every other smartphone display to shame: At 960×640 and bearing a 326ppi pixel density, it offered pixels smaller than the human eye could detect. The iPhone 4 was also encased front and back by slim slabs of glass, and ringed by an aluminum rim. This is why it is looked more beautiful. The visual conceit was slick, and Apple received kudos for its smart industrial design refresh.
Apple's second generation iPhone had been debuted in the summer of 2008. Internally, it was largely identical to its predecessor: same processor, identical type of display, same 2.0 megapixel camera, and same amount of memory. The new era has begun when iPhone 3G came to market. But the iPhone 3G, as the name implied, now supported 3G network operability, as well as GPS.
Five years ago today, Apple unveiled the original iPhone to the world. It wasn't a tightly kept secret, shrouded in mystery and speculation like more recent Apple announcements, but it was arguably the world's most anticipated gadget launch.Although its form factor -- a capacitive touchscreen candy bar hasn't dramatically changed over the years, each iteration of the iPhone has yielded important improvements. Let's take a look back at how the iPhone revolutionized what we thought a phone could be.
