iOS 7-based update locks out non-developers
A newly-released version of the Find My iPhone iOS app, 2.0.3, is breaking some access to the service. Most people trying to launch the updated app will see an error message, insisting that they "must be a registered iOS developer and have iCloud configured on iOS 7.0 Beta" to make it past the login screen. Devices can still be tracked via the Find My iPhone web app.
Apple appears to have accidentally pushed pre-release code to the public. The company is expected to launch iOS 7 next month, and is likely working on overhauled versions of all its first-party apps to better suit the look and features of the new OS. Today's update in fact changes the Find My iPhone icon to a new, flatter design, more consistent with iOS 7.
