The iPhone 4 introduced some key features that are still the base of the current iPhones, some of those features that debuted with the iPhone 4 are: FaceTime, LED flash, front-facing and rear camera, Retina display, the tier of GB’s to choose from, (even though the iPhone 4 started with 8GB’s), HD video recording and a few more amenities.

The 3.5-inch 4th generation iPhone came with a stainless steel frame, which doubled as an antenna, with aluminosilicate glass. also the A4 system-on-chip was introduced with the iOS 4. The liquid crystal display had a pixel density of 326 pixels per inch.

The iPhone 4 was the longest running Apple flagship iPhone model which lasted for fifteen months, and it had the longest lifespan of any iPhone ever produced. The iPhone 4 had a pre-ordered market success of selling over 600,000 units, but it wasn’t without its problems, two of its biggest problems were the Retina display, there were problems with the balance of the necessary pixels, as well as with the antenna design, which affected the device with a weak cellular signal, this caused the user to experience many dropped calls. The iPhone 4 would become Apple’s base foundation for improving and perfecting the iPhones to follow.
