All my contacts disappeared after i made an entry. I went to settings and there is nothing regardng syncing for contacts. Do i have to manually put them back in? Does anyone know how to fix this?
This problem has come up before, but I'm not sure I've ever had success fixing it. I will however offer the same advice, just in case it works this time.
First, lets make sure your contacts are really gone.
Check the Search field. If there is anything in this, it will limit your contacts to what matches. That can easily be nothing.
Second, if you have a red ribbon on the left page that says Groups, tap it and see if you have the right address book and/or group selected. The ribbon my not be there, depending on how your contacts are set up.
A restart is always a good idea. Hold down the power button until the power off slider appears. Slide it off. When the iPad finishes shutting down, hold down the power button again until the Apple logo appears.
If your contacts are still in limbo, there is one other possibility.
If you have not synced your iPad to iTunes since the contacts disappeared, they may still be in your last backup.
Open iTunes (without the iPad connected) go to Preferences, and the Devices tab. You'll see a list of backups, only one per device that you sync with iTunes. Check the dates.
While you are there, turn off auto-sync. It will make it easier to manage when you iPad syncs in the future. It's important now, because you do no want the iPad to start syncing when you plug it in. The first thing it would do is overwrite your backup.
If that looks good you can choose to restore your iPad. You will lose everything stored in a app since the last time you backed up the iPad. So go trough all your apps first and save the important files, photos, whatever to the computer, or email them to yourself.
Connect your iPad.
In iTunes, under the Device list, right click on your iPad and choose Restore from Backup. Be sure it says 'from Backup', not just Restore. Select the backup from the list and cross your fingers.
Hopefully that worked. If not, and you don't have your contacts backed up in some other program, you are stuck with entering them again manually.
In the future I recommend syncing your Contacts with an online service like Google. It will be a lot easier to recover them if anything happens to your iPad.
To use a GMail account to sync contacts you have to set it up as an Exchange account. Here are the instructions, in case you decide to use Google.
