Last month we posted a report titled "Nokia Declares War on Samsung with Exciting New Android Smartphones at Stunning Prices." Today, at Microsoft's Build 2014 developer conference, we got a glimpse at their new Windows Phone 8.1 OS that will be introducing Cortana, their synthetic cousin to Apple's Siri. Yet the surprise that emerged from this event was Nokia's introduction of new Windows 8.1 smartphones that will start rolling out in the US this July. The new models, in my humble opinion, are squarely aimed at both Apple's iPhone 5S and 5C. This is definitely going up the ante for Apple's upcoming iPhone 6 due to debut this fall.
