change apple ID on other devices
I have an old ipod touch that still has the old apple ID attached to it. When the ID was changed a couple of years ago, the ipod touch continued to work as far as photo stream and manage icloud account, etc. Now for some reason it's stopped synching and backing up. How do I change the apple ID on the ipod touch to the same as the iphone? Can I do it through icloud.com? Do I need to erase the ipod touch or can it just be updated online? When I go to Apple ID the old one shows up and is grayed out so I can't do it there. When I go to "manage storage" it says icloud storage details are currently unavailable, try again later". I can go to "general" > usage >" and it says the same, icloud details unavailable. Do I need to reset the device? TIA
