Are the text messages still there after restoring iPhone 4 using iTunes? Have they all been deleted?

The text messages have been deleted after restoration. It is best to back up in advance before restoration.

The steps are as follows:

1. Open iTunes and click Edit -> Preferences -> Devices on the menu bar. There will be various time points for device backup. From here, you can restore all the data at that point in time. These data include original data such as photos, address books, memos, etc.

Note: The device needs to be connected to the computer that was originally backed up before it can be restored, and the restored data is only limited to the data backed up at that time, and subsequent data will be lost.

2. Recovery operation: Open iTunes and press the keyboard shortcut Ctrl+S to bring up the iTunes sidebar. Then select the device first, then click the restore backup button. Then in the pop-up window, select the time point to restore the data, and then click the restore button. iTunes will automatically complete the restore operation.

Note: During the automatic recovery process, to avoid errors, please do not perform any operations on the iOS device.
