What is a good free antivirus for iPhone 4?

hi i am new to owning an iPhone an I have never heard the word jail broken? Was just wondering if someone could explain that to me. An I to was wondering about the antivirus app. I owned an android up until acouple of days ago. I went threw 2 different phones in two days before I got my iPhone because my androids crashed on me an I thought it was a virus but I'm not sure what happend. So I was fearful something is gonna happen to my iPhone.

People trying to make a buck with unneeded software. It's called Free Enterprise.

There isn't one.

As long as the iPhone is not jailbroken, one is not needed.

There are no antivirus apps for the iPhone. Not like there are for a PC.

If you haven't jailbroken your phone, there is no malware in the wild that can affect it anyway.

None.

There is no need for a non jailbroken iphone.

.If you really want something go ahead and use one,,your money

As alreay stated in the first 3 response, non is needed for a non jailbroken iphone.

Do you have a jailbroken iphone?

Usually you see an app like cydia.

did you buy the phone from an authorize apple dealer or second hand?

Why do you think you need antivirus on your phone?

No only jailbroken phones.

if you bought it from verizon then your phone should be safe.

I've never owned one, but from reading these forum they are more prone to viruses than an iphone.
