I restored my iphone and set it up as new etc and when I opened the Read It Later app it said something like. "Do you want to use the account previously used on this device"? I clicked yes and it logged me in with my details automatocally. I restored my phone so how come it still saved my password for that app? Its the only app I've came across thats done it though. Just concerned for when I sell or give this phone away in the future. I'm jailbroken so iwipe should completely wipe my phone?
