As we reported some time back, Apple was looking into the idea of ditching sim cards for the next iPhone, selling directly from its own store or online. It's an idea that looked good on paper, but according to a report, it's an idea that didn't go down well with the networks.Sim card manufacturer Gemalto was apparently asked to create a new integrated sim with 'subscriber identification information' for the carriers, which would allow phone buyers in Europe to simply pick up a new iPhone 5 directly from an Apple outlet. Customers would then be able to choose their network at the time of purchase or via a download at the app store. Goodbye network stores in other words.According to the Daily Telegraph, the networks were less-than-keen on the idea and made it clear to Apple that they would no longer subsidise phones if it went ahead with the new sims. Networks currently pay £375 to Apple for iPhones, subsidising them for anyone who signs up for a contract.A senior source at a mobile operator told the newspaper: 'Apple has long been trying to build closer and closer relationships and cut out the operators. But this time they have been sent back to the drawing board with their tails between their legs.'
