I opened BlackBerry Messenger just to be sure the contacts were there, and they were. I then went through Enterprise Activation. I have done 3 battery pulls and don't receive that message any longer. It might be worth a try. I had gone back down to 4.3.0.115 prior to this because I too wanted my BB Messenger contacts to show up without this error. But now I am back on 4.5.0.42.
