Hello Ladyland,


         Go to Setting on your cell then find> Accounts and sync, then find your account
Highlight it push and release! And a second window will pop-up! And now hit the menu button on your
cell and an option remove account will show. Highlight and delete it and the account will be gone on ICS.


    If on Gingerbread? Go to settings>Accounts & Sync>find account and highlight push and release on account, now another box pop's open and you will see your account highlight it and click the remove button showing on screen. And hit the remove option.


       They are the only two O/S I know about, hope it is one of them, Good Luck
