How does Apple 4 uninstall weather and stock software and uninstall unnecessary software? What is prison break?

The so-called mobile phone jailbreak is aimed at the iPhone, and it is aimed at cracking the iPhone operating system that restricts users' storage and reading rights. The jailbroken iPhone has read and write access to the bottom of the system, allowing the iPhone to use the cracked App Store software program for free.

After jailbreaking, you can delete the software that comes with these systems, such as stocks and weather. But after uninstalling, there are many problems. Although it has been refreshed for a while, it may lead to the instability of the mobile phone, so my approach is to install infinidock after jailbreaking and drag all the icons that are not commonly used to the place where the taskbar can't see them.
