If my company provides me with an iphone, can they spy on my facebook and texts?

I want to know if they can spy on my facebook activity (specifically messages and private posts, passwords, etc) on the content of my texts to my friends and family, and call logs. And what laws this kind of activity might be violating, as well as the basis for civil suit, and what ways i can use to detect spy apps on the phone.

About the only good thing about Apple is their security, if your company provdes you with the iphone if they wanted to monitor you they would indeed need an app. And they would need to declare to you that the app was monitoring you to be legal. As they proved it to you they have the right to audit it, for security purposes, they have the right to check what you install, what you post using their device but not the actual content. That however comes under your employment contract, the phone is theirs, they are giving you it to do your job, they can configure it as they see fit to do the job but as its apple all they can do is add the configuration you need and thats about it, you would then sync it to your own itunes and it then ties to you. They can monitor your calls, the numbers dialled and costings but not the contents unless they tell you.
So in short, they have rihgt to see what you install and who you call, and if they tell you they can record your calls, but they HAVE to tell you. If they don't then its the same rights as anyone else, they don't have any but the phone is theirs, they can wipe it or recall it at any time.

Yes and i would also it is not yours ---it is a security issue. What don't you understand about a company owned phone

Take a look at: http://www.parental-controls-software.net usually, you need to get physical access to install spy app on the target phone.
