Is it necessary for iPhone4s to upgrade iOS5 to iOS6? Or ios7?

Upgrade it, I'm 4s, system, than 5.A few systems are much cooler. Those flashbacks are due to non-appstore** software such as PP Assistant. I didn't have a problem with the one I used.

No, if you are the system, it is perfect, there is no need to upgrade, you will get stuck after upgrading, because the configuration of the 4 series is not high,

If you have 4s, you need to consider upgrading, and I am also 4s. Personally, I feel that iOS7 is more convenient and user-friendly than 6, and the flattened interface is fresher and more atmospheric. Especially the version that has just been launched, it is optimized for previous phones, and you can turn off the view animation, so you don't have to worry about the system not being smooth after upgrading.

However, the version that has just been pushed out will have a little flaw and more loopholes. You can't downgrade after upgrading, and if you don't get used to it after upgrading, you have to use it hard. It's up to you whether you upgrade or not.

If you want to upgrade, then with a heart to accept new things, by the way, with a little courage to boldly upgrade!

Upgrade io7 to think clearly,It's not very easy to use,If it's an American version of the machine,Be careful that you can't use GPRS to surf the Internet after upgrading,You have to upgrade the card.。

It is recommended to upgrade to ios7, and soon all apps will only support ios7, and it is very easy to use now.

It feels like it's still up. Rise to. There is optimized acceleration.

There's no need for the original system to be fine.

There is one more iMessage, which can be sent for free between iOS 5. When locked, you can press the round key twice to take a photo quickly. There's an extra gesture function, which can replace some of the round key functions, but it's not very convenient, and there's also a notification center that can be pulled down, which is good.

But the opening ** is a lot slower.

Just upgrade it directly. Upgrade to 6 and you can't jailbreak, at least not at the moment. So choose carefully.

It is possible to upgrade to ios6 but currently ios6 cannot be jailbroken.

It is very convenient to upgrade directly by plugging in the computer and using iTunes to keep up with the new.

iTunes upgrade or mobile wifi upgrade, both can be used.

At present, there is no cracking news about ios6, and it is estimated that there is no jailbreak.

If you have jailbroken at the moment, or ios5, it is not recommended to upgrade, and it will not be able to descend if you go up to 6. If yes, you can upgrade.

The steps are as follows:1Back up your data with iTunes. Connect iTunes, right-click on your iPhone, select Backup, and the backup will be successful. This backup backs up text and **, does not include programs.

2.If you are currently jailbroken, after the backup is complete, hold down the shift key and click Restore Restore. If you are not currently jailbroken, you can hold down shift to select the upgrade, and then select the firmware you have downloaded to upgrade directly.

3.After upgrading, set it to an existing iPhone and you'll be prompted if you want to restore from a backup. After the restoration, the upgrade is complete.

Note: Directly on the device through the wireless network upgrade, is OTA upgrade, there is no instability. However, there is a risk that after the full version, a new version may not be able to be flushed after it is closed. So, it is generally recommended to upgrade thoroughly through iTunes.

The advantage of direct upgrade is that the upgrade is fast, and there is no need to restore to the factory state, so you don't have to worry about the loss of software data in the machine.

Upgrading iOS6 with itune is much faster than the previous ios upgrade,It is estimated that Apple officially added a server,It will not take more than half an hour,The upgrade will not overwrite your contacts,But iOS6 can't jailbreak yet,If it's a jailbreak user,You still have to think twice before upgrading。 As for upgrading through firmware, there are already many tutorials on the Internet.

Hello, my 4S and steak have been successfully upgraded, all through the waln** upgrade, there is no instability problem! The program software and contacts will not be deleted, and you can also back up beforehand!

There will still be an address book.,The game has to be re-downloaded by yourself.。

iPhone4s can't update from iOS 6 to iOS 7 now, only to the latest iOS or etc.

Apple has turned off the following system verification for the iPhone 4S, which means that you can only update to iOS or above.

It is recommended that you do not upgrade, after upgrading the card.
