I've used LastPass for a while now, and after Regina's awesome session on security I think I'm going to upgrade to LastPass Premium ...mainly because I'd like to use it on my iPhone.
I do try to read and research before I jump into anything, though. The iPhone app sounds confusing. It doesn't seem to work in Safari? Does that mean the app has its own browser? Does LastPass for iPhone work on app passwords/logins?...like for the Facebook app or Skype?
