The wonder phone that "changes everything, again" has finally hit the stores in five countries, namely the United States, the United Kingdom, Germany, France and Japan.

The sales began at 7am local time for stores in the U.S. while for U.K, Germany, France and Japan it was 8am local time. The iPhone 4 is the biggest leap from it's first generation predecessor. On the design side we have a whole new body that is made out of glass, instead of plastic as in older generations.
The phone boasts a resolution of 960x640 with its new "Retina Display" making it the highest-resolution phone screen ever and on the other side we have the A4 processor, 512 Mb of Ram, a front-facing camera for video calls and a 5 megapixel camera that shoots HD videos in 720p. The software is powered by iOS 4 which supports multitasking, folders, unified inbox and a whole bunch of other new features.
"FaceTime" is the most prominent feature of the new iPhone 4 which allows users to make free video calls on Wi-Fi.
However! apart from all the excitement and craze for this new smartphone, some users have had bad experiences as well. The phone seems to be having a couple of issues of its own so only time will tell if these issues affect the sales of the phone in any way.
