IPhone jailbreak, okay

1. The system has high authority, so you can optimize the system yourself and modify the system files. You can install more software with high system permissions and realize more advanced functions! For example: send files with other devices via Bluetooth, SMS receipt, call attribution, file management, browser download plug-in, flash plug-in, content management, etc.

2. The cracked software can be installed.

3. You can change the theme, icon, SMS ringtone and so on to create a personalized mobile phone.

4. You can flexibly manage the system or other files with the help of third-party file management software, such as using iPhone as a mobile hard disk (USB flash drive).

Disadvantages of jailbreaking:

1. It costs electricity. After jailbreaking, some processes will stay in the jailbreaking state. Depending on the number of system-level software (deb format) installed, the power consumption speed will increase by about 1% ~2% after jailbreaking.

2. It may cause system instability. With high system authority, we are also in danger of system collapse. Can you understand this truth? You can modify it, but you can't guarantee to correct it forever. Therefore, it is better to have system-level software than to abuse it, and don't install it indiscriminately if you don't understand the purpose.

3. When the new mobile phone firmware version comes out, it can't be updated in time. Every new version of firmware will fix the jailbreak vulnerability of the previous version, making jailbreak invalid. Therefore, if it is necessary to maintain the function after jailbreak, we must wait for the release of the new jailbreak program before upgrading the corresponding mobile phone firmware version.

4. There are small bugs in the process of jailbreak, but it doesn't affect the use very much, so you have to be patient to solve them.
