If you haven’t already checked this out, you should. Sync has free audiobooks (totally painless sign up and they don’t spam you with email) and their selection tends to be one current(ish) novel and a classic. I’ve still got my downloads from last summer and was really disappointed I hadn’t found them sooner. This summer’s offerings have been pretty great as well.
In related news, DoggCatcher has decided to STOP WORKING on my phone. Mother fucker. So I’m open to your podcatching app recommendations. Currently I’m using iSyncr to grab some of my faves from iTunes and Stitcher for the ones that update while I’m at work.
