Hi there. I'm about to sell my iPhone 3G and noticed that even after wiping the phone, Cydia (and Appsidy) still tie my purchases from the Cydia store to my phone even without logging in. I logged in with Google, and so I just went to the account authorization page for my Google account and revoked access for the Cydia Store and Appsidy. Is there anything else I should do to prevent the next owner from making Cydia Store / Appsidy purchases with my account or misc other potential wrongdoing?
