I had this problem a couple months ago its from t mobile upgrading thier switches. Their towers are not carrying the correct signals. What happens is blackberrys need incoming, outgoing, and something else. Your tmobile switches are not configured correctly and it's only functioning with two of the three required signals for blackberrys. If it's not working after this whole outage is done call tmobile incessantly and make them fix this.
