[Is Android less secure than iPhone?]

Many people have told me that iPhone's are more secure than Androids just because Apple does not allow malicious applications in their app store.

With that said, if malicious apps are not much of a security concern than what is?

What exactly are these security flaws that you are referring to?

How would one go about exploiting those security flaws?

This is just for my own general knowledge :).

I've heard mixed answers from this question and was wondering what the hak5 community thought about it.
