Carphone Warehouse claims to have sold 11,000 iPhones over the first weekend of the Apple device's launch on Nov 9. This is slightly above its earlier estimates of 10,000, and represents one fifth of the retailer's initial iPhone stock. O2, meanwhile, says that 8,000 customers registered an iPhone with the network on Nov 9, of which a quarter did so within one hour of the launch. The announcement contradicts earlier reports, which suggested that initial sales failed to meet expectations, in part due to less visible hype and crowded stores than at the US launch, on Jun 29. Carphone, the UK's and Europe's largest mobile retailer, and Telefonica's O2 UK are the exclusive partners of Apple in the UK, and the only stores alongside Apple stores that sell the 8GB smartphone, which costs USD560. O2 earlier predicted that it would sell 200,000 devices by New Year - below analysts estimates of about 350,000. In Germany, where the phone launched on the same day, its exclusive carrier and retailer T-Mobile says it sold 10,000 phones over the weekend.
