Can I export a list of downloaded iPhone apps from iTunes?
You could do this with a few Terminal commands.

First, open the Terminal by going to Applications -> Utilities -> Terminal.  Then, paste in the following and press return.

cd ~/Music/iTunes/iTunes\ Media/Mobile\ Applications


Then, paste in this next command and press return.

ls &gt; ~/my_apps.txt


Now, in your Home folder (/Users/yourusername/), there will be a text file called my_apps.txt containing a list of all of your apps.
