What does it mean that Apple's mobile phone weather forecast is over 80 degrees?

It's over 80 degrees. You should set the temperature to Fahrenheit. You can change it to Celsius.

In 2004, Apple convened more than 1000 internal employees to form an iPhone R&D team, and launched a highly confidential project called "Project Purple", among which Jonathan Ive, the behind-the-scenes designer of the iPhone, was one. At that time, Steve Jobs, CEO of Apple, shifted his focus from tablet computers such as iPad to mobile phones. Apple and AT & amp； T secretly cooperated to create some software and hardware devices-Cingular wireless network at that time-AT&; T also gave Apple investment and great freedom, spending about $65.438+0.5 billion in 30 months. In exchange, Apple promised that the iPhone sold in the United States would be handed over to AT & amp； T exclusive sales.
