When I ran into Rob Kao of SmrtGuard yesterday at Mobile World Congress I convinced him to go on camera for a couple minutes and give us an update on where things are at. SmrtGuard recently released a free version of their premium mobile security application, and with pre-MWC rumors talking about RIM releasing their own "BlackBerry shield" service, some of our comment posters made reference to the timing of these events maybe being a little too coincidental. Check out the video above to see what Rob had to say.
