Apple’s upcoming wearable device, based on iOS, will run third-party applications and, furthermore, may come equipped with an App Store, according to two sources with knowledge of the new device. It is currently unclear if the App Store will be full-fledged, like on the iPhone and iPad, or if it will be a special section with in the iPhone App Store for apps that play nicely with the new wearable device. A small handful of high-profile social network and services companies with apps on the iPhone and iPad App Store have already been seeded with a pre-release version of the Apple SDK (Software Development Kit) for wearables under strict non-disclosure agreements. One of the developers with access to the pre-release SDK is Facebook, according to a source. Facebook is also said to be finishing up work on an iOS 8-optimized version of its iPhone app with improved notifications.
