There aren't any viruses for the mac! Forget idevices. Think about it. If you download music, and the music has a virus, and the virus goes to your playlist, it can't do anything. All the apps are sandboxed. And besides media and the appstore (which has a heavy duty review board), where else would you get viruses from?
There was one, created by an 11 year old. http://www.ipodhacks.com/article.php?sid=2482 That is the only one, though.
Wow, what an evil child. I bet he'll grow to be an evil villian. Good thing I'm non-jailbroken (for now)
omfg if i saw that kid there are not even words to what i would do....how could you do that to such a beautiful device
