No bmi have not started their trials yet, later in the year or early next. It is being done on two 320's so that will make it interesting for regular pax who will try it on other a/c.
Personally I hate the idea of phones used in flight. Most people tend to forget they are talking to someone miles away on a phone and revert to shouting the distance. Whoever you are, you are not that important enough to disturb anyone in earshot with your one way conversation.
