iPhone security architecture
<p>I want to study in detail about security architecture that iphone has implemented. after searching on internet, the only useful material that i found is iphone reference library. Where i am now a days studying the Architecture of OS and then i will seduty the "secure coding guide".</p>

<p>I was wondering, if some of you guys, can lead me to some nice article or something which covers iphone security in general or in detail besides iphone official sites. </p>

<p>thanks,</p>
