Technically the question was "Can BlackBerrys get viruses like computer ones?"
And the answer to that is and always will be "no". Unless BlackBerrys start running on Windows
I have to agree with JSanders and NJBB on this. The answer as of this posting is no.
If in the future, there would be a virus for BlackBerry devices, these posts are time stamped, and anyone can see at the time they were posted. At that time, this thread would most likely be closed due to not being active in 6+ months.
