Yesterday was a bad day at the iOS office for Apple. First, because a Russian iPhone app called Find and Call made it onto the App Store, despite being designed to harvest users’ address books then send their friends spam texts. The first example of malware on iOS, and speedily removed from the App Store. The second problem was even more serious: a bug with Apple’s app DRM code that saw a series of corrupted app updates made available in its store, which were then crashing for users. The bug has since been fixed.
