Security App for the IPhone 5

if you don't jailbreak and if you use safari

then you don't need to do anything

there are a lot of myths about security in the range of people who are not working with computer on a professional level

This would have been better as a follow-up in your other thread:

rather than starting a new thread.

In any case, if you mean that you want to protect your passwords and other information should your iPhone be lost or stolen, there are a number of third-party apps for that purpose. I use 1Password, which I can sync among all my devices and computers and am quite satisfied with it, but there are other, similar products you can look into.

For future questions, it really helps if you're completely explicit about what you are asking. Otherwise we have to keep either guessing or trying to get the necessary information from you.

Regards.
