Nearly all software applications, let it be computer or electronic based, are susceptible to viruses and trojans. To answer your question, it all depends on the virus, trojan, or malware loaded onto your iPod and how secure the software platform of your device is. Viruses are more malicious than trojans, so in retrospect your iPod touch should be okay and your identity should be safe. The operative word here is: “should,” as there is no guarantees. Most malicious code (viruses, trojans, etc.) are made to target a specific platform such as: Microsoft Windows. So generally, your iPod’s interface should be untouched. Hope this helps.
