For those Blackberry or any PDA with a camera users who do not have the software simply go to:
(must be logged in) to grab your private email address that will send your attached photos directly to your account. I have been using this for awhile which allows fast integration into my Flickr photo stream as well as saving a copy of the picture in my email.
