The reason for Apple's slowness: Apple's content distribution is handled by Akamai, a North American CDN manufacturer, but Akamai does not distribute content for Apple in China. Apple entrusted the authoritative DNS of the Xiangshen Zhenguan domain name to Akamai, and when the recursive DNS of the domestic ISP to the authoritative DNS of Akamai resolved the relevant domain name of Apple, the IP address of North America was basically returned, so the user **Apple software was basically from North America**, so the speed was slow.

In view of the fact that Apple's slow performance is caused by Akamai's authoritative DNS service, 114DNS is optimized for this purpose, and through relevant technical processing, users are directed to Akamai's servers in Hong Kong and South Korea to distribute content for Apple as much as possible. Therefore, you only need to change the DNS address of the iPhone iPad to the public DNS service address of 114DNS, and you can greatly improve the speed of the WiFi** Apple software.

Apple does not officially support system downgrades.

1 When Apple launches a new system version, it will turn off the system verification of the old version, and the system verification version that is turned off means that it will no longer be able to flash the version that should be turned off for verification. Only the latest version can be used. So if the phone is working properly, there is no need to upgrade.

Upgrades are usually new features for ** phones, and it doesn't make much sense to upgrade older phones and may slow down your phone.

2 Some old versions of the system, after jailbreaking, use the Aisi assistant to flash the machine to achieve the purpose of downgrading, but the operation is more complicated, and jailbreaking is risky, so it is not recommended to operate in this way.

If the official has not closed the verification channel of the old version, it can be reverted to the old version, and if the channel has been closed, it cannot be restored.

There is only one possibility, that is, when you flash the new system to upgrade the old system, you can flash back the original old system, if there is no backup, Apple's current system is basically up and down, all of which are closed and cannot be flashed back.

For example, after the iPhone 3G version is upgraded, you can directly restore the firmware to downgrade; If the 3GS version cannot be downgraded directly by restoring the firmware, it is recommended that you pay attention to Apple's official ** whether there is a follow-up upgrade for the system to improve the previous bugs (defects).
