The first two apps I put on the phone are keepassdroid and dropbox.
I have blogged about these in the past and now I have my phone synced to the same keepass database. For all those i-phone users there is of course an i-phone version too. It all works a treat so I still do not need to know any of my passwords.
One slight issue I had, my PC version of keepass was out of date so I had to upgrade that to get the two keepass clients to work together.
