Yesterday afternoon, Apple mistakenly updated the Find My iPhone app in the App Store, but the update was only compatible with app developers using the iOS 7 beta.

A 2.0.3 version of the Find My iPhone app was released on Thursday. Its updates were described as "bug fixes and stability improvements" on the App Store. Apple users that download the app, however, were informed that they their devices were not compatible with the update. 

Users that tried to use the updated app encountered an error message that read: "Developer Account Required. You must be a registered iOS developer and have iCloud configured on iOS 7.0 Beta to use this version of Find My iPhone."

Apparently, the update to the app was only compatible with those app designers who using the beta version of Apple's iOS 7. In fact, the updated Find My iPhone icon is even configured as an iOS 7 app, which looks flatter than previous designs.

It is likely that Apple made a mistake and released the update in the App Store prematurely. Apple has not released a statement regarding the mistake. The company has, however, updated the app for non-developers.

Rumors have it that iOS 7 will be released to the public at a September iPhone event.

Changes in iOS 7 include adjustments to the size and shape of app icons and other commonly used items, as well as differences in iconography and typography.

The app icons for the iOS 7 will now feature a "superellipse" shape which differs from the simple radii values for rounded corners with which app programmers are familiar.

Classic icons, which feature outlines with color-fills, will be used in iOS 7, but there will also be the addition of icons that consist of pure outlines without any color.

iOS7 is expected to be easier, faster and more enjoyable for users. Apps will look different, but Apple claims they will have the same familiar feel users are used to. As a result relearning should not be necessary in order to operate iOS 7.

Some of the biggest new iOS 7 features include AirDrop for iOS and Control Center.
