Up until now, Apple's held out on offering carrier billing for services like iTunes and the App Store. But it looks like that's coming to an end, at least in Germany. As reported by TechCrunch, Apple seems to have quietly flipped the switch on this feature, which lets digital goods be charged directly to a phone bill, for people using O2's wireless network. A spokesperson for Telefonica, the owner of O2, confirmed to the publication it is in fact working with Apple on carrier billing. If you're an O2 wireless customer in that country, it means you can start charging Apple Music, iTunes, App Store and iBooks purchases directly to your monthly bill. Access is limited at the moment, but Telefonica says everyone on O2 will get it by the beginning of November.
