What if There's a Virus on the iPhone?

If you have jailbroken your phone and downloaded an app that you think may have harmed your phone, you can try restarting it. If this does not fix the problem, you should plug your phone into iTunes and try restoring it to factory settings. This will remove your jailbreak, but it should fix your problem. Keep in mind that many viruses are created with the intent of stealing sensitive information such as email passwords andbanking information. If you think any of this may have been compromised, it is wise to change all of your passwords, even after you have removed the jailbreak.
