There has been concern about stock levels of some variations of the new iPhone, but it hasn't stopped Apple racking up huge sales in the first weekend.Yes, another weekend launch, another record weekend. Although that was probably helped by two models being available on the opening day this time. In total, nine million iPhone 5s and iPhone 5c smartphones were sold over that first weekend, easily smashing through the figure for last year, when the iPhone 5 shifted five million units during the first weekend of trade.So despite concerns about the lack of a market for the iPhone 5c and the lack of stock of the iPhone 5s (especially in the gold variation), Apple has come up trumps once more. The boss is obviously pleased.'This is our best iPhone launch yet - more than nine million new iPhones sold - a new record for first weekend sales,' said Apple's CEO, Tim Cook, rather enthusiastically. 'The demand for the new iPhones has been incredible, and while we've sold out of our initial supply of iPhone 5s, stores continue to receive new iPhone shipments regularly. We appreciate everyone's patience and are working hard to build enough new iPhones for everyone.'That last remark does connect with what we heard yesterday about Apple trying to boost production of the much sought-after gold version of the iPhone 5s. Although with long dates on all iPhone models right now, customers would probably be happy with a stock drop of any right now.With new iPads expected next month, it could be an impressive e fourth quarter financially for Apple. Perhaps even another record breaker.
