At first read, I'm not sure what to make of this article. On one level it overstates the obvious. When you have an entirely open system, bad guys may use it as a way to get malware onto your phone. You need to use some discernment. Okay. Got it.
Then in the next breath she brings up iPhone with its tightly controlled ecosystem. Sure it is possible that something could slip by, but it is highly unlikely and so far the only malware that has been found to work on an iPhone requires jailbreaking the phone. She didn't specify jailbreaking so I have to assume she means the official ecosystem which at this point doesn't make sense. Even Steve Gibson in an interview with Leo LaPorte on Security Now said that security was an advantage of Apple's closed system with the iPhone.
I almost think the author lumped iPhone in order to sell more copies of SMobile. I wonder where the report that this article was based on came from? Oh yeah, it was from SMobile, a company I've never heard of before. Now I get it.
