I did not deregister my previous 2 computers, how do I do that now, as I have a new computer and many things do not want to sync. Please help as I am a bit on the elderly side.
iPhone 4, iOS 6.1.4
What do you mean by 'deregister' ?
If you want to deauthorise your account on your previous computers : Deauthorize your computer using iTunes - Apple Support
If you mean changing the computer that you sync your phone to : Syncing to a "New" Computer or replacing a "crashed" Hard Drive
Some of the steps on that page have changed slightly (it was written for a previous version of iTunes) :
5, is now File > Devices > Transfer Purchases
6, 'Reset Warnings' at the bottom of the phone's Summary tab in iTunes
7, File > Devices > Back Up
8, File > Devices > Restore from Backup (or Restore Backup button on the Summary tab)
I did not deregister my previous computers - how do i do it without deregistering my new computer? Please help as I am not so young anymore.
