I just bought an iPhone 4S and it's an amazing phone. Now I'm going to sell off my old 3GS so I was looking for to remove it from my Apple ID since I won't be the owner of it any longer. Where can I do this? It feels like I've checked everywhere but I can't seem to find any solution.
I found http://support.apple.com/kb/HT4627 which states:
" Removing an associated device or computer from an Apple ID
To remove a device or computer from your Apple ID:
Now the problem is when I sign in and view my account I don't have anything called "Manage Devices" shown in that area. All I got is Apple-ID, Payment Info, Billing Address, Region, Computer Auth., Purchase History, Ping and Settings with Nickname, Reviews, Alert Me, Rec & Ping Posting + Passes. There is nothing that says Manage Devices.
So, anyone know what I should do? Since I will be selling of the 3GS I don't need nor want that phones serial number to be connected to my Apple ID any more.
Thanks in advance for any help.
