I have been using this program for over a year now and it is really excellent.
Although, it is possible to send single files from the phone to the computer, you have to do it one picture at a one, restarting the process each time.
Photo Retriever automates that, transferring everything over, then importing the pictures into iPhoto. Perfect.
$12 is nothing for the convenience that this utility gives you IMHO.
It does what it does pretty simply and well.
