How about Apple 4 SiO 7. 1. 1 jailbreak?

If the mobile phone runs smoothly and has good performance in all aspects, jailbreaking is not recommended, and various problems will occur after jailbreaking. If you don't understand mobile phones, it is recommended to be careful to escape from prison.

1. Apple has always opposed jailbreak, so after the recent successful jailbreak of iOS 8, Apple couldn't sit still. Recently, the company added a provision in the shopping policy of retail stores that jailbreak devices do not enjoy warranty to warn users not to try to jailbreak their iPhone and iPad.

2. Unauthorized modification of iPhone software violates the iPhone software license agreement. The most common way to modify iPhone software is jailbreaking, which is why Apple emphasizes and strongly advises users not to jailbreak, because jailbreaking devices will not enjoy the warranty service for software failures. Apple has repeatedly stressed that jailbreaking will bring "harm" to the device, such as the following:

(1) Stability: devices often crash, and native or third-party applications of iOS devices will flash back, and data contained in the applications will be lost.

(2) Security vulnerabilities: jailbroken devices are easy to be used by criminals, and users' personal information is threatened by theft at any time, and devices will be more vulnerable to virus attacks.

(3) Shortened battery life: After a full charge, the jailbreak equipment can no longer maintain the original battery life.

Audio/data loss: during the call, there will be audio loss, slow or unstable data connection, delay or error in positioning data.

(4) Service interruption: voice mail, weather, stock and other applications will be interrupted with the jailbreak of the device.

(5) Impact on software upgrade: Arranging plug-ins on iOS devices after jailbreaking is likely to cause irreparable losses and affect future system updates.
