4S upgrade ios7 without 3G 20

Hello, it's a system issue, sit back and wait for a patch or downgrade! At present, ios7 has just come out of the unstable, and there are many vulnerabilities! Imperfect! Personally recommend downgrading! Wait for the stabilization to be upgraded.

I'm talking about UI because the visual aesthetic is different from person to person. There are many advantages after iOS 7 upgrade, but the disadvantages cannot be ignored.

2. The control center slides up from the bottom of the screen, adding switch functions such as wifi, **, flashlight, etc.

3. Third-party input methods can be used. (But it's not sure if there is an input method for the nine-grid palace).

4: You can block incoming calls and text messages. (No doubt is true).

5. Added the security and anti-theft function, bound to the Apple ID, others must enter the correct Apple ID to activate, even if the system is re-flashed, it is also required to enter the Apple ID.

Disadvantages: 1. Multi-task management has been replaced by real background running software, and the current market is a device with small memory except for iPhone 5 memory that has reached 1G, so the memory is obviously insufficient. (As a result, the operation is not smooth, and the keyboard sometimes does not pop up).

2. Power consumption, no doubt that this is certain. Really in the background, there is also a shake phone wallpaper exchange, which is enough to increase power consumption.

3. Other shortcomings will be discovered and supplemented later.

Recommendation: Personally, I recommend not to upgrade unless you like the new UI and need to use security features. In fact, ios7 has strict hardware requirements, especially memory, 4, 4s will seem a bit insufficient.

Hope it helps! Hope! Thank you!

Solution: iPhone 4S Stuck after Upgrading to iOS7:

Reducing the amount of data stored in your device can significantly improve performance. In the settings, you can see how much storage space you have left, and you can also see how much space each app is using in descending order. If you find that your storage space is too full, uninstall apps that take up a lot of space and you feel are dispensable.

2. Disable automatic background processes.

Automatic background processes are a convenient feature, but if they slow down the system, the convenience is not as worthy.

3. Reduce dynamic effects.

Go to Settings, General, Accessibility and turn on Reduce Motion Effects.

4. Turn off the blur and transparency effect.

Go to Settings, General, Accessibility and turn on Contrast Enhancement.

Samsung... Apple is on the verge of decline... What will come out in the future, 6 ah, 6s, you will find out... It's so powerless.

You can take it to a dedicated Apple repair shop to upgrade, if you can't make sure you get it right. 4S can be upgraded to iOS 7.

The experience is certainly not as good as it was when iOS6.

My 4 is up and it feels okay.

1. Apple mobile phone 4S uses 3G network, you only need to go to the settings to turn on the 3G network mode.

2. Click Settings - Cellular Data, you can see the option to start 3G on the interface of turning on the cellular network, and you can use the 3G network by turning on the cellular network and the 3G network.

3. But Apple4S does not support mobile 3G, only supports Telecom and Unicom3G, so even if the 3G network is turned on, the mobile phone is installed with a mobile ** card, and the 3G network will not be displayed.

Go and upgrade your phone number to 3G and turn on the 3G switch.

As long as the mobile phone number is 3G, it will do

Can be upgraded. I've been upgrading for over a month. It is not recommended that you upgrade. I think the battery drains quickly after upgrading, and the operation is a bit sluggish.

1. Back up to the computer, that is, after connecting the device, select "Sync", then the backup will be made in the computer, and the data will be stored in the iTunes file package of the C drive.

2. Use iCloud to back up to the cloud database. After connecting the device with iTunes, select the device name, then go to "Summary", select "Backup to iCloud" in the backup chatter option, and select Apps.

There are three ways to upgrade iOS 7:

1. OTA update.

In other words, as long as your device is in the list of iOS 7 upgrades, you can find "Settings" - General "- Software Update" on your device, select iOS 7, and then the device will be connected to the Internet** and installed. Wi-Fi is recommended, but it should be noted that the App Store** limit has been increased to 100MB on a data network.

2. Use iTunes to update your device.

Apple has released iTunes today, after the user**, in the "Summary" "Version", select "Check for updates", then it will enter the **iOS 7 firmware, and install it.

First, connect the device to the latest version of iTunes with a data cable (the address is here), then manually ** iOS 7 firmware, then close the meditation on iTunes, hold down shift, and click "Restore" at the same time, and select the corresponding version of iOS 7 firmware for recovery.
