If you thought the iPhone craze wouldn’t last then you were wrong. On June 24, Apple introduced the iPhone 4 in the United States, Britain, France, Germany, and Japan. It sold more than 1.7 million units in the first 3 days, the most successful product launch in Apple’s history.

The iPhone 4 is a newer and more high-tech design of the last 3GS mobile device. It was immediately a huge hit because, compared to the old version, the new device is 24% thinner, features an entire flat backing, a stainless-steel edge, and longer battery life. It also includes an easy to use camera on the front that can take high-definition videos at 30 frames per second and allows free video conferencing with other iPhone 4 owners.

The consumer demand for the product was so unexpectedly high that it caused rowdy crowds and lines of hundreds of determined customers in front of Apple retail stores. Unfortunately, the supply for the iPhone 4 was low and Apple wasn’t able to collect enough parts for more versions of the device.

Though the black colored version of the iPhone 4 came out on Thursday, the white colored one was also expected to come out but will instead be released at the end of the month. Both models, priced at $199 for the 16GB and $299 for the 32GB, are selling out quickly.
