Oh no! That doesn't sound good. Hopefully your contacts were backed up to iCloud, if so you may be able to restore them using the following information:
Restore from an iCloud backup
- Go to Settings > General > Reset, then choose “Erase all content and settings.”
- In the Setup Assistant, sign in to iCloud, choose “Restore from a Backup,” then choose from a list of your backups in iCloud.
Welcome to the Apple Community.
The difficulty in restoring iCloud data from a back up is that the back up is older than the current version on iCloud and anything that is restored gets removed again when an iCloud sync occurs.
- Ensure the device is connected to your local network.
- Start the restore from iCloud back up.
- Allow the devices settings to restore (watch for the confirmation of completion).
- As the apps begin to restore pull the connection to your router WAN port (the one that goes to the telephone point).
- Wait for the time out confirmation.
- Navigate to settings > iCloud and turn off contact syncing (keep contacts when prompted).
- Reconnect the router to the internet and let the restore process complete.
- Delete any iCloud contacts from iCloud.com on a computer.
- Navigate to settings > iCloud and turn on contact syncing (merge contacts when prompted).
May I suggest that you carry out a back up to iTunes before you try anything, that way should things become even worse, you can at least restore back to where you are now.
In regards to recovering deleted items such as this, you need to check your Recycle Bin on your PC or Trash or your Mac. It is for situations like these that you should NEVER setup these receptacles to delete immediately but leave them to be deleted at a later point manually which will give you some time to review the items and determine if you really mean for them to be eliminated from your computer.
Also, it is good practice in general to backup all of the contents of your computer to an external hard drive monthly, if you can. I, for one, make sure I not only specifically make a back up of the iPhone data (I just did it 2 days ago), I also make back ups of my iPhone Back Up files, iTunes Music Library, iTunes Library XML file, Microsoft Outlook Contacts (which I sync with the iPhone), and anything I create, edit or update as a file on my computer.
In this way you are able to recover lost iPhone contacts when it comes to trying to find ways to rescue iPhone files that have been deleted for any reason. File recovery is expensive, time consuming and can be inaccurate at best, especially when a good percentage of the files you recover can be corrupted and unusable. In a word, there are several ways to recover deleted iPhone data, you can have a try!
