Iphone jailbreak has the following disadvantages:

1. The jailbroken iOS device is not covered by the warranty (the system can be restored before maintenance);

2. Impact on system security:

(1) After jailbreaking, the system will have a default root password. If you don't modify it, others will invade your system? ;

(2) Install the third-party input method, and the third party will also store and use all your input information (such as SMS, user information and password);

3. System instability: Many applications that are suddenly restricted by the system are high-authority applications. If there are bugs in these functions, the system may crash;

4. Reduce system performance: Consider many limitations of Apple (such as the previous input method API). In addition, restricting the first-generation and second-generation devices to use multitasking is to save memory and restrict VPN persistent connection to reduce battery consumption.

As for the benefits of jailbreaking, the most important thing is that you can use the functions and software applications prohibited by iphone.
