Is there a way to protect email using passcode in iPhone? I dont want to put passcode on phone, it is quite annoying, i just want to protect email. Is there any way to do so?
You will have to jailbreak your iPhone to password-protect the Mail app. Sorry, there's no other way. :-)

I ran across this article, which has three apps for password protecting iOS apps.


Lockdown Pro
FolderLock
Locktopus


All are paid apps.

This article mentions an app called iAppLocker. It is free. Hope this helps you!
