Whats App updated its initial blog post to confirm that it will extend support Black Berry OS, Black Berry 10, Nokia S40 and Nokia Symbian S60 until June 30, 2017.
Jones was the talk of the launch, as he lined up alongside the other coaches, Rob Howley, Vern Cotter, Guy Noves, Conor O’Shea and Joe Schmidt, to preview the championship, which starts in 10 days time.
Earlier this year, the Facebook-owned company announced that older versions of Android and i OS, as well as Black Berry and Nokia devices would no longer be supported by the chat app.
The company has advised anyone running any of the named devices to buy a new one before the end of 2016.
England go into the tournament as favourites, having enjoyed a remarkable change in fortunes under Jones.
He took over after the debacle of the World Cup in October 2015 - England were the first hosts ever to be eliminated at the group stage - but led them to an unbeaten 2016, winning a record-equalling 14 Tests in succession, including a first Six Nations Grand Slam since 2003 and a first ever three-Test series win in Australia.
