Slide 1 of 4
The Original iPhone (or iPhone 2G)
When: The iPhone was announced January 9, 2007 and released June 29, 2007.
The Hype: Its release marked the end of a simpler era when flip phones were still acceptable and traffic accidents were mainly caused by people texting in the street, not checking email or Buzzfeed.
It's no wonder, then, that the release of the first iPhone – dubbed the "JesusPhone" by eager techgeeks -- was an event of epic proportions. The Guardian caught up with Greg Packer, first in line at the Apple Store on Fifth Avenue in New York City, who waited 109 hours in the muggy summer heat for a phone. Why? "All you want is there," he told the outlet.
At least he wasn't lonely. Other techgeeks waited with him, including Vincent Nguyen, 11th in line, who flew in from Arizona for the occasion.
Numbers: By September 9, 2007, just 74 days after its release, Apple announced that 1 million iPhones had been sold.

iPhone 3G and iPhone 3GS
When: The 3G was introduced on June 9, 2008. The 3GS was released almost exactly a year later, on June 19, 2009.
The Hype: The mania surrounding the release of the original iPhone was hard to top, but tech bloggers attempted it anyway. In the months leading up to the release, gadget blogs whipped themselves and their readers into an iFrenzy (a tradition that clearly has not died).
Upgrades: The second-generation iPhone had a better battery life, incorporated 3G technology and introduced popular features like assisted GPS and the App store. The 3GS was even faster, with a better built-in camera.
Numbers: By July 12, 2008, just three days after its release, Apple announced that 1 million 3G iPhones had been sold. "iPhone 3G had a stunning opening weekend," Apple CEO Steve Jobs had said in a press release. "It took 74 days to sell the first 1 million original iPhones, so the new iPhone 3G is clearly off to a great start around the world." The company also sold 1 million iPhone 3GS units its first weekend.

iPhone 4 and iPhone 4S
When: The iPhone 4 was announced June 7, 2010, and released on June 24, 2010. The iPhone 4S was announced on October 4, 2011, and released on October 14, 2011.
The Hype: The already hefty level of public anticipation was enhanced by the infamous Gizmodo leak in which a hapless Apple software engineer left a prototype of the iPhone 4 at a Redwood City, Calif., beer garden. The phone was discovered, and swiftly sold to Gizmodo for $5,000 cash. The tech website wasted no time in publishing a "definitive guide" on the yet to be released model.
Upgrades: With the iPhone 4 came the birth of videocalling (i.e. FaceTime) a higher resolution display, and improved camera capabilities. The 4S introduced us to Siri, a feature that some considered to be more amusing than useful.
Numbers: By June 26, 2010, just three days after its release, Apple announced that it had sold 1.4 million units of the iPhone 4. Apple said it sold over 4 million units of the iPhone 4S the first weekend it hit shelves.
Correction: An earlier version of this slide misstated the date for the announcement of the iPhone 4S. The phone was announced on October 4, 2011.

Slide 4 of 4
When: The iPhone 5 was released September 21, 2012.
Hype: Pre-release hype, as usual, was intense. But this time, the post-release gripe was even more so. The main complaint: Apple had done away with Google Maps, substituting it with Apple's own vastly inferior version. Also…there was a new charger. It was chaos, at least until Apple allowed users to reinstall Google Maps and people got over not being able to use their iPhone chargers on their phones.
Upgrades: Despite all the online venom, the iPhone 5, while not drastically different from its predecessor, had noticeably faster wireless internet speed, better battery life, and improved Siri features.
Numbers: By June 24, 2012, just three days after its launch, Apple announced that it had sold over 5 million units of the iPhone 5.
