How does Iphone4 delete SMS with one click? It escaped from prison.

Iphone itself does not have the function of deleting short messages with one click, but it can be realized through itunes.

Step 1: synchronize the backup data to your itunes (generally, it will be synchronized automatically as long as the iphone is connected to itunes, unless it is set to not synchronize automatically).

Step 2: Click Settings-General-(Pull to the bottom of the menu) Restore-Erase all contents and settings on the iphone. You can safely erase it because there is already a backup in itunes.

Step 3: Connect iphone to itunes. Right-click the device in itunes, restore the data, and then check Info.

About 5 minutes (because all the recovery includes the application, depending on the time of your application), your iphone data will be exactly the same as before, except that the SMS is empty.

Although it is more troublesome than one-click deletion, for users who have not escaped from prison, this method should be the fastest to delete short messages, especially those that have not been deleted for more than a year, which is much faster than deleting one by one.
