Josep just found a new Google Updater application that allows you to install all of the Google applications on your BlackBerry from one location. The new application does not bring all that much more to the table and this is not the first time that Google has tried such a thing. The new part in all this is that they have added a nicer interface and a new application icon for Picasa which is really just a homepage link. The versions of all the applications are all the same.
You can get the app OTA at this link
Note: For those who are keeping notes the Gmail application is still at version 1.1 and has not been upgraded to 1.5 like the regular Java app.
