When was the first time you got a smartphone?

pu1. I'm not sure about the very early model, but I think it's right to see when the iPhone was first released.
The iPhone was first released in the United States on June 29, 2007.

OK

pu2. Before the iPhone, there was something similar to a mobile phone, such as BlackBerry or Palm, which is now merged into HP
From what I saw in the previous article, I heard that LG made the most similar thing to the current mobile phone that uses the touch screen like now. Just because LG doesn't remember, Apple claims copyright. lol

OK

pu3. The reason why it has become so popular is because Apple has made almost all of the basic concepts of using an app on a touch screen, so I think it's right to say it's an iPhone. I think it's just that competitors jumped in and Android came out and became popular as it is now. In that sense, the timing of Samsung's Galaxy S's release seems important, but Samsung's Galaxy S was first unveiled at CITA 2010 held in Las Vegas on March 23, 2010. It was first released in Korea through SK Telecom on June 24, 2010, three months after that
