Hello All, I'm a newbie to C25K and I've just downloaded the podcasts to my iphone. I played a bit of the first one just to see if it had downloaded OK, and after 5 minutes or so I decided to bite the bullet and go out for my first session. How do I restart the podcast? it just keeps going back to the place it was at before. Do I have to let it play all the way through before I can listen from the start?
