Is it good or bad to escape from Apple's mobile phone?

It's not good to escape from prison. It's just a matter of opinion whether it's necessary to escape from prison.

First, you need to know your own needs. If you don't escape from prison, the mobile phone function has met your needs. Then it is best not to jailbreak, and because of the closedness of the Ios system, the overall security and stability of the system can be guaranteed.

And if the function of mobile phone is not enough to meet your needs without jailbreaking (such as changing theme, font and installing more interesting plug-ins), then you can of course choose jailbreaking.

Of course, you need to know that these plug-ins may lead to unstable system operation after jailbreak, such as occasional restart, crash, power consumption and so on. Of course, if you just install some mature and stable plug-ins after jailbreaking, it will not affect the normal use of the mobile phone.
