iPhone 5C

Although the iPhone 5 had been a runaway success, there were some problems with the case bending, as well as battery issues with units built through January 2013 (see the iPhone 5 page for more details). The iPhone 5C was designed to address bending with its thicker plastic polycarbonate enclosure.

iPhone 5

With the iPhone 5, Apple left behind the 3.5″ display every previous iPhone had used, replacing it with a taller (or wider – in landscape mode) 4″ screen displaying 1136 x 640 pixels, the same 16:9 aspect ratio of HD TV. That’s 18.3% more pixels.

iPhone 4S

The iPhone 4S looks like the iPhone 4, but there are a lot of differences under the hood. Hardware includes Apple’s dual-core A5 processor, superior graphics, and support for both GSM and CDMA networks. And to top it off, there’s Siri.

iPhone 4 (GSM)

With the iPhone 4, Apple introduced its Retina Display. The screen was the same size as on previous iPhones, but with twice the vertical and horizontal resolution. It was a revelation.

iPhone 3GS

The iPhone 3G had been a step forward in some areas – especially in adding 3G data support – but in other areas it was no better than the original iPhone. With the iPhone 3GS, Apple took a few more steps forward with a faster processor, a better camera, video capability, and a 32 GB option.
