My Ubuntu One Control Center on my computer uses one account. My Ubuntu One app on my android phone uses a different one. I want to change my account on my computer to the one that my phone uses but I can't figure out how.
Go to your ubuntu one account
Remove your computer from the account you no longer wish to use.
Create new account, connect the account for your phone.
