"So, as long as you haven't jailbroken your device, your iPhone, iPod touch, or iPad should be safe from viruses… There aren't any identified iPhone viruses in the wild-there have only been proof-of-concept viruses and attacks."

Nope.
Maybe if the iPhones were jailbroken you could do that, but realistically, that's not going to happen.

No…
