You must use 1Password application for your mobile phone. Now you can take your information with you so that it's always on hand. Mobile versions of 1Password are available for iPhone OS and Palm OS and more data portability options are coming. Using this application you can save all your data in one folder and you can give it one password.

As per my knowledge you have to use PasswordWallet application for your iphone to protect private information. PasswordWallet encrypts your passwords, usernames, PIN numbers, combinations and personal notes with extremely fast Blowfish encryption. Use the auto-typing feature to log in to your favorite web sites using PasswordWallet's built-in browser. You can even edit entries while navigating a site. You can get this application from it's official site.
