Washington: Apple has reportedly issued an updated iOS 7.0.4 version to fix a bug with the FaceTime calls.

The issue caused some calls to fail through the feature. The tech giant has also addressed other issue with the App Store that enabled a user to complete an app or in-app purchase without full authorization, Mashable reports. The report said that those who use older iPods are not eligible for the 7.0.4 upgrade, but have received an upgrade of iOS 6.1.5, that also fixes the same FaceTime bug.
