Background and Identification ¶
Released on June 29, 2007 the first iPhone spun the cell phone world around and took it in a completely new direction. It took the idea of having a phone at your fingertips at all times and turned it into having your personal computer/phone/assistant at your fingertips at all times, leading us into the era of smartphone-dominated consumers.
Since the release of the iPhone in 2007, there have been four new iterations—iPhone 3G, iPhone 3GS, iPhone 4, iPhone 4S—each adding new features, faster processing, and improved graphics.
With different models came different levels of repairability. The 3GS's front glass is replaceable separate from the display assembly (the 4 and 4S glasses are not), and the iPhone 4 was rebuilt for easier repair of the rear panel and battery.
Though Apple may tell you otherwise, all of these devices are user-serviceable with the help of our repair guides found in each of the device pages above.
