What are the disadvantages of iphone jailbreaking?
1, if Apple's mobile phone escapes from prison, even if the device is still under warranty, Apple may not guarantee the mobile phone;

2. It needs electricity. After jailbreaking, the system will always keep some processes in jailbreaking state, because themes and the like are always running, and some plug-ins will always run in the background, which will consume some power;

3. It may lead to instability of your mobile phone system. After the mobile phone is jailbroken, you can easily delete or modify any system files with the highest authority of the mobile phone. If an application accidentally deleted or installed modifies important system files, it will directly lead to the crash of your mobile phone system. If the phone is not jailbroken, no program can delete or modify the system files.

4. After jailbreak, many services of Apple official website may be affected, such as mobile phone retrieval function;

You can't upgrade the new version of the system at will. If Apple updates the IOS system, because the system has been jailbroken, if you update the system, your jailbreak will be invalid, which will directly lead to the unavailability of many applications you installed before. And Apple's iOS firmware can only be upgraded, not downgraded. Therefore, if you still need to maintain the function after jailbreaking, it is best to wait until the new jailbreaking program is released, and then formally upgrade the corresponding mobile phone firmware version.

The first step to crack an iOS device (iPhone, iPad or iPod touch) is to install a plug-in and unlock it after jailbreaking. Jailbreak enables third-party management tools to fully access all directories of iOS devices (iPhone, iPad or iPod touch) and install plug-ins and pirated software that change system functions.

More specifically, jailbreaking refers to taking advantage of some loopholes in the iOS system, obtaining the root rights of iOS through instructions, and then changing some programs to strengthen the functions of devices and break through the closed environment.

IOS devices (iPhone, iPad or iPod touch) were turned off when they were first bought. As ordinary users, we can't get the root right of iPhoneOS, and we can't install some software into the mobile phone. We can only buy software through the iTunes Store in iTunes (of course, most commonly used software is free, and now some software can be directly pirated without jailbreaking), and then through Apple-approved methods (this process enables Apple to ensure that the applications installed by users on devices are signed by developers and have not been tampered with. In this way, Apple ensures the security of user information), and copies the software we legally get to the mobile phone.

But in this way, our users are firmly bound to Apple's jurisdiction. However, some useful software may not be in Apple's interest. Or in Apple's view, they may have violated consumers' information security, so they can't enter the iTunes Store.

For example, as an excellent multi-screen interactive product, WiPlug works with iphone and ipad to achieve more powerful functions. It's like projecting the whole screen of a mobile phone or tablet onto a TV. It has a broad application space in business. When there is another meeting, it is not necessary for everyone to take a notebook and connect the projector. Just connect the projector to WiPlug, and then everyone's mobile phones can directly demonstrate PPT on their mobile phones, and then display it on the projector.

The above operation requires advanced permissions, and Apple does not allow it. In order to make better use of our iPhone or iPad, we had to escape from prison. It is not necessary to escape from prison, but it will be more refreshing, convenient and fun to use your mobile phone after you get out of prison. After jailbreaking, you can use a lot of software for free, which can further improve the usability of the mobile phone.
