I have a 16gb 2nd gen touch. Reading the manual it says how to delete a podcast or song from the touch. Doing what it says I am not able to do so. It says connect touch and open itunes click on triangle next to device. it opens up music, podcasts etc. I click on podcasts and I highlight the podcast I want deleted and when I hit the delete button on keyboard nothing happens. I have to delete the podcast from itunes then sync the touch. How can you delete a podcast from the device only? thank you.
