So, the ability to root an iOS device via an exploit doesn't count as malware? Interesting.
Could an exploit be used to install malware? Yes.
So, no, it doesn't count.
iOS definitely isn't without security issues, but it doesn't have the same malware issues that plague Android.
The reports of malware on android phones are greatly exaggerated.
At this point I see both platforms at the same basic risk for getting infected. The possibility is there, but it is not nearly enough to worry about.
