The iPhone 5 is a smartphone designed and marketed by Apple Inc. It is the sixth generation of the iPhone , succeeding the iPhone 4S and preceding the iPhone 5S and iPhone 5C. Formally unveiled as part of a press event on September 12, 2012, it was released on September 21, 2012.  The iPhone 5 is the first iPhone to be announced in September and setting a trend for subsequent iPhone releases, the first iPhone be completely developed under the guidance of Tim Cook and the last iPhone to be overseen by Steve Jobs.
Since March 2013: "Loving it is easy. That's why so many people do." 
The iPhone 5 featured major design changes in comparison to its predecessor. These included an aluminum-based body which was thinner and lighter than previous models, a taller screen with a nearly 16:9 aspect ratio , the Apple A6 system-on-chip , LTE support, and Lightning , a new compact dock connector which replaced the 30-pin design used by previous iPhone models. This was the second Apple phone to include its new Sony made 8MP camera, which was first introduced on the iPhone 4S.
At the unveiling, Apple announced the iPhone 5 and also introduced new iPod Nano and iPod Touch models. They also stated that pre-orders would be accepted starting September 14, 2012.  Over two million pre-orders were received within 24 hours.  Initial demand for the new phone exceeded the record set by its predecessor, the iPhone 4S , by selling over 5 million units in the first three days.  On November 30, 2012, Apple added an unlocked version of the iPhone 5 to their online US store, with the 16 GB model starting at US$649.  
The iPhone 5 was officially discontinued by Apple on September 10, 2013 with the announcement of its successors, the iPhone 5S and the iPhone 5C. While the 5C shared almost the same internal hardware as the iPhone 5, the 5C used a lower-cost poly-carbonate plastic case in place of the original 5's aluminum form. The introduction of the 5C deviated from Apple's previous market strategy, where the previous iPhone model would remain in production, but sold at a lower price point below the new model. 
A SIM (Subscriber Identity Module) card contains all of the information associated with your iPhone. If you would like to change mobile devices, but you want to keep your existing information, you can remove the SIM card from your iPhone and insert it into another phone. You can get a SIM card out of an iPhone using a special SIM removal tool or, in some cases, a simple paperclip, but the exact process may vary slightly depending on your iPhone model.
