Wait until 3.0 comes out and use your bluetooth.Or rather, podcasts.
Sometimes I'm on the bus, and I don't feel like scrummaging around for my headphones, or putting them on, but I also don't want to use the speaker.
Is there a way to just listen through the earpiece?
Good advice but keep in mind this thread is from 2009. I doubt they need this anymore.Try iEarMusik available through the AppStore - https://itunes.apple.com/us/app/iearmusik/id543335277?mt=8
I would take it even further and be so bold to suggest no one will notice. As people walking around with phones to their heads is no longer unusual. If anything someone may ask where is your phone, these days. If you don't have it out and to your head.Well if you're hand is covering the back, then no one will know your phone is upside down. They may just find it strange you never say anything into it.

The app earplay does this for music. I'm still looking for one for podcasts
