1. When Apple was established, the influence and popularity of the Apple brand were not as high as they are now. So when it released the second-generation Apple computer, Apple started giving away stickers in the box.

2. Because stickers were very popular in the United States at that time, giving away stickers not only catered to users’ preferences, but also provided free advertising for their own brands. The Apple stickers that were given away at first were colorful, but later, as the Apple LOGO changed, they became pure white.

3. Another way to say the sticker is to commemorate Steve Jobs, the founder and CEO of Apple. Jobs' influence on Apple was indeed profound, and even had influence and contribution to the entire industry.

On January 9, 2007, Jobs launched the first-generation iPhone at the Apple Global Software Developers Annual Conference 2007 at the Masconi Convention Center in San Francisco. The two initial models are the 4GB version priced at $499 and the 8GB version priced at $599. They were officially launched in the United States at 6 pm local time on June 29, 2007.

Hundreds of Apple fans queued up early outside Apple stores across the United States to buy. Due to the craze and enthusiastic sales response caused by the newly launched iPhone, some media hailed it as the "God Phone". The first-generation iPhone was launched in the United Kingdom, France, and Germany in November 2007, and in Ireland and Austria in the spring of 2008.

Apple first entered the mobile phone market in 2005. Although in theory, this device integrated mobile and music, in practice, it did not arouse much interest from consumers.
