iOS Keychain Privacy Issue
iOS apps persist keychain data even after the app is deleted.<p>For example, this allows Facebook to track you across multiple installations even if you intentionally uninstall the app.<p>There is no way to delete this data without jailbreak.<p>IMHO this is a huge privacy issue that needs more awareness.<p>source:
