iPhone 4 went on sale on June 29th, 2007 at 6:00 p.m. local time in the United States. iPhone was available in a 4GB model for $499 and an 8GB model for $599 initially.
Subsequently Apple released iPhone 3G in 2008, iPhone 3GS in 2009 and iPhone 4 in 2010. Apple is expected to release the next generation of iPhone sometimes in late 2011. While many speculate that the next iPhone might get a new design, our sources said that it will retain similar iPhone 4 form factor. Curiously, our sources never used the moniker “iPhone 5” to describe the next iPhone. Back in December 2010, one particular source mentioned that there would be no new iPhone during WWDC 2011. It turned ut to be true. To answer a particular question, our particular source is not Phil Schiller.
Happy 4th birthday, iPhone.
