BlackBerry's full touch phone Z10, released at the end of January this year, has continued to be popular with fans. It has also been sold out in Canada and the United Kingdom for a day. However, whether BlackBerry can regain business and government users is the key to its success. Recently, the German Federal Information Security Office approved a procurement plan for 5000 BlackBerry Z10s from the government. It is understood that the Secusmart data encryption technology of BlackBerry is the main reason for the favor of the German government.
