A Russian developer has discovered a way of getting in-app purchases from iOS apps for free, reports say. The hack can be performed without jailbreaking a device, and should moreover work on any iOS device running iOS 3.0 or later, even up to the beta of iOS 6. The technique involves installing a pair of certificates and changing DNS details under Wi-Fi settings. When making purchases from apps a pop-up from in-appstore.com should appear instead, which despite an unrelated message, allows people to skip paying.
