Superstar singer Alicia Keys was named the Blackberry Global Creative Director during the Blackberry 10 launch today, though it's not evident yet what the job will actually entail. According to clues on her Twitter account, Keys was very recently an iPhone user. Apparently, on three days ago she sent a tweet to her account using an iPhone.

Despite her iPhone usage, Keys says her and the iPhone are "broken up". She maintained that her and the Blackberry 10 are now "exclusively dating."
