One current limitation of Windows Phone 7 is the inability to download and manage podcasts on your device over-the-air. Awhile back we reported on a free app called simply Podcasts! which at least allowed you to stream any podcast, though not save. The app worked very well, but if you didn't want to use your precious 3G data minutes, then you were out of luck.
BringCast ($1.99, trial available) gets around this by finally allowing you to download audio and video podcasts. The selection of 'casts is limited but that's fine as you can request your favorite to be added and more importantly, you can type in the RSS URL or OMPL file to import your selection.
The app worked flawlessly on our end, though sometimes it was a bit stuttery on screen transitions. Still, for a v1.0 app we really have no complaints--the download screen is nice, it integrates with Zune's history and we dig the "what's new" screen. Pretty solid. The trial is fully functional except you get a nag screen on 1st launch and you are limited to any three feeds--but that's more than enough to tell you if it's worth the $1.99. Grab it here in the Marketplace.
