WASHINGTON – Whether you choose to talk on an iPhone or an Android says something about your personality, a new survey shows.

Gadget recycling company Gazelle has found that iPhone and iPad users are the most optimistic and sociable among all mobile device users, while those with Blackberrys are the most negative about the future.

The Daily Mail reports that a third of all blackberry users surveyed believe that if something can go wrong for them, it will. And they rarely count on good things to happen.

But, the good news for Android users is that the study found you are the hardest working.
