UPDATE!!!
After i had my blackberry updated yesterday unsuccessful, I called several times DATA from Bell and they where unable to solve my problem.
Every time the answer was the same “4 to 24 hours to get the system up to date".
I called then customer service and i told them that i will like to cancel the service since they (Bell) cannot provide me the service that i signed for.
They passed the call to a supervisor that contact the technical support and they did the "SYSTEM UPDATE" again.
In 30 seconds the unit was working on 1XEVDO.
Make sure that you insist to cancel the contract since they cannot provide the service.
Hope that this will help other people.
Take care.
