LastPass for BlackBerry has been deprecated.
LastPass for BlackBerry (4.2.1+) is an application that allows you to carry your LastPass data around with you. Its intended use is for when you do not have access to a computer, but need to access stored information for a Secure Note or a Site.
LastPass for BlackBerry allows you to download all of your LastPass information from the server and store it in a secure, encrypted file that can be saved to your BlackBerry. As always, this data can only be unlocked using your email address and password.
Starting with BlackBerry OS 5.0, LastPass for BlackBerry features a built-in browser that will automatically fill your login information for each of your saved Sites.
