I've got a computer at home, at work and a iphone that I always have on me. I listen to most podcasts at work, and I often find that I will leave a podcast unfinished and want to listen to the rest at the gym, in the car or back at home. I've considered syncing my phone with my work machine, but I would still need to connect my iphone before I left work everyday. Is there a third party application or service that can get all my devices in sync? I would not mind leaving iTunes behind to manage my podcasts either. Thoughts?
