Are there any details on how the fingerprinting worked? And why it was needed? Not being an iOS dev, after a few minutes of Googling it looks like: - The blessed way to get a unique device ID is identifierForVendor [1]. Is the issue that this changes when users uninstall/reinstall the Uber app? - The deprecated way to get an ID that persisted across installs was accessing the UDID directly [2] Can an iOS dev or someone better informed than I comment?
