Facebook (FB) - Get Report owned WhatsApp has once again extended its service date for the Blackberry (BBRY) BB10, according to a tweet from Blackberry's senior VP Alex Thurber, this time until December 31, 2017.

The messenger app was originally scheduled to stop working on the BB10 device at the end of last year, but the company extended the support through the first half of this year.

WhatsApp had announced earlier this month that it would officially end support for the Blackberry 10 and OS devices, as well as the Nokia NOK S40 and Symbian S60 phones by the end of the month, tech site MobileSyrup said.

The company said the platforms don't offer the capabilities needed to expand the app's features going forward.

Amazon has some work to do with Whole Foods: Organic grocer Whole Foods (WFM) needs Amazon's (AMZN) - Get Report tech know-how, and it needs it very quickly to slash prices.

TheStreet's Lindsay Rittenhousewent shopping online at Ohio stores to see how Whole Foods stacked up against Walmart Stores Inc. (WMT) - Get Report and rival grocer Kroger (KR) - Get Report . While the results may not be shocking, they show just how much Amazon will have to cut for Whole Foods to be on equal footing with some of its competitors.

The cost of eight everyday food items at Whole Foods, TheStreet found, were nearly double those of the ones at Walmart, but Kroger undercut them both. Whole Foods' basket cost $38.29; Walmart's, $19.86; and Kroger's, $16.58.

With data as shocking as this, it's no wonder Whole Foods founder John Mackey is in love with Amazon.

Tesla's market cap is now more than $60 billion and climbing, despite the company continuing to lose money. Ford's (F) - Get Report market clocks in at $44.7 billion, while General Motors (GM) - Get Report stands at $51.9 billion.
