Bian Xiao: Now that the official version of iOS 7 has been released, iPhone 4 can be upgraded directly to iOS 7. You can select General in the iPhone 4's settings, and then select the option to check for updates. iPhone 4 will prompt for updates available. After confirming the update, the iPhone 4 itself will complete the firmware download and update. After restart, you can use iPhone 4 with iOS 7 system. If wireless speeds aren't ideal, connect your iPhone 4 to your computer and open iTunes. At this point the software will have the same upgrade prompt. After confirmation can be updated, download speed faster than with wireless network. In addition, it should be noted that due to hardware limitations, the iPhone 4 will be stuck after upgrading to iOS 7, and the iPhone 4 cannot be downgraded after upgrading, so consider carefully before upgrading.

OTA upgrade: ios7.1 method (not recommended).

1. Connect iPhone \ iPad \ iTouch to a stable WiFi or 3G network (upgrading 3G network is not recommended due to large firmware capacity).

2. Open Settings-General-Software Updates-and click [Download and Install].

3. Agree to terms and conditions and wait for firmware download and installation to complete.

Note:

Jailbroken iPhone\iPad\ iTouch may not be able to use the OTA upgrade method.

OTA upgrade is not recommended, which may lead to SHSH unavailability. Some netizens feedback that firmware upgrade through OTA is unstable.

iTunes upgrade/restore iOS 7.1.

1. Use PP Assistant (Win) firmware download to download the latest firmware version of the corresponding phone model (it is not recommended to use iTunes to upgrade directly, because it is very slow to download firmware using iTunes);

How do I differentiate between iPhone/iPad/iTouch firmware?

2. Connect iPhone/iPad/iTouch to PC and open iTunes

3. Hold down the Shift key on your keyboard and tap iTunes Update/Restore.

iTunes will pop up a dialog window-please select the firmware you downloaded with PP Assistant (Win)-click Update-wait for iTunes to run.

5. To successfully upgrade/restore iOS 7, you need to activate your device (please prompt to complete the steps)!

Note:

Recovery via iTunes results in the erasure of all data on your iOS device. It is recommended to backup important data first.

Jailbroken iPhone/iPad/iTouch may report Unknown error when upgrading/restoring with iTunes. Please rest assured! If iPhone/iPad/iTouch upgrade/restore fails, it will automatically enter recovery mode. Please connect iTunes and restore the ios7 firmware again.

In fact, the biggest highlight of this new ios 7.1 official version is to fit the iPad perfectly, so upgrading on the new iPad air should be the best without any mistakes. Of course, it's not impossible for you to insist on upgrading the system in Apple products.
