Apple 4S supports upgrading to ios8, but it is stuck, so it is better to stay in ios7.

1. Apple 4S can be brushed from any version.

2. The most suitable for Apple's 4S is that it is the most stable and can give full play to the 4S hardware performance. The more than the version is a bit stuck to use. The above version has a serious sense of stuttering.

4S does not support downgrading. If you go up, you can't come down. But the current one is special because Apple usually closes the verification of the old version after a few hours after releasing the new version.

So, you can try to brush with iTunes. If you can't brush it, then you can't brush it again, and if you can brush it, the action must be fast! Within 24 hours, the verification is completely closed.

The steps are as follows: 1. Back up your device data with iTunes.

3. Open iTunes, hold down the shift key, click "Recover", and select the firmware you just downloaded to flash it.

You can brush the latest version or if you want to jailbreak, one day Apple closes the verification, and it will be troublesome to jailbreak.

What is the latest official, you can only brush what you have, you don't have to choose. Currently it is.
