Four years ago today (June 29), Apple launched the first multi-touch smartphone, the iPhone. People thought that it will sell pretty well, but it’s not going to change the smartphone industry — but soon it became one of the most selling devices in the world.

What happened after that….? More than 10 million Apps were download within 3 days of the release, the figure exceeded 14,000,000,000 in June 2011, Apple’s share price tripled since the iPhone was first released etc.
