On January 10, 2007, Steve Jobs demonstrated a new intelligent mobile phone---iPhone, as well as the iOS system, which has changed history.
At that time Windows Mobile、Palm OS、Symbian and BlackBerry OS were all active on the mobile stage.
The first generation of iPhone did not support 3G, didn't support the third-app, didn't support copy and paste text, didn't support multiple tasks, didn't support email attachments, didn't support MMS, Exchange, Office Editor and so on.
