LAS VEGAS--Trade shows like CTIA Wireless 2013 are often the scene of phone and device introductions. Handset makers often hope to grab conference-goers with new and innovative devices, but this year's CTIA show is decidedly different. This year, there are almost no new devices to note. Handset makers, starting with Apple (NASDAQ:AAPL) and now including the likes of BlackBerry (NASDAQ:BBRY), Nokia (NYSE:NOK) and Samsung Electronics, prefer to launch their new devices at dedicated events, where they can control the flow of the headlines. As a result, few device makers use trade shows as the launching pads for their new gadgets. However, there are a few new handsets worth discussing at this year's CTIA Wireless. Check out this slideshow to see them all.
