Apple's stock is down again today, falling below 500, and it's dragging the whole stock market down with it. Much of the decline can be attributed to the Wall Street Journal's report citing unnamed sources that demand for the iPhone 5 is weak. Yet analysts are saying, after checking with their sources in the supply chain, that demand continues to be robust. We'll likely find out the real truth next week when Apple reports their December quarter results and tells what they expect for the March quarter. In the meantime, it doesn't help sales that bloggers like me keep passing along rumors of the Next iPhone. According to AppleInsider, Apple is currently testing two prototypes of future iPhones and will begin preliminary builds of the iPhone 5S in March, suggesting that it will come to market in a June/July time frame. No doubt some people thinking of upgrading to the iPhone 5 will now, on the basis of these rumors, consider waiting until the Next Model.
