European mobile operators have started building stock of the new 'nano Sim' amid expectations it will be used in the next generation of Apple iPhone, the Financial Times reports. While Apple has yet to give any details of the new device, market rumours suggest a launch in September or October. The new Sim card design was recently approved by the European standards institute, based on a design backed by Apple. Operators expect that the iPhone will feature the nano Sim in a slimmed down design, two sources with knowledge of the situation told the paper, and have begun to store millions of the cards in warehouses in anticipation of high demand for the new iPhone. Apple declined to comment. One informed person said that the major networks were keen to be ahead of demand this time, after some ran short of micro Sims when they were first deployed in the iPhone. The source added that the iPhone 5 was likely to be similar sized as the iPhone 4, although slimmer and with a fully metal body.
