You can safely store passwords for all of the electronic devices you use by keeping them on a list in your cell phone's MemoPad application. This article is about the BlackBerry Storm cell phone but you can do the same thing on most cell phones. When you do this, you'll have the password for any of your devices or applications on hand when you need them. You also don't have to worry about being locked out of an application because you've exceeded the number of allowed logon attempts.
