You should see it when you plug it in if you're running Windows 7. The problem you'll have is that DoubleTwist doesn't currently support MTP. Of course they suggest their AirSync program to be able to do it (which is $4.99). However, for $4.99 you could pick up DoggCatcher, which is a good podcast app. Regardless of the issues with DoubleTwist, you should still be able to view your N4 on your PC. Make sure that the MTP mode is actually on. Go to Settings, Storage, then when at the storage screen hit the menu button and you'll see USB computer connection, tap it, then make sure MTP is checked. Then see if you can at least see it when you plug it into your PC. If all you want to do is transfer files you can do that through MTP (or through Wi-Fi). Remember that the podcasts downloaded from iTunes are usually in MP3 format so you can just move them to your phone via MTP or Wi-Fi and play them with any program that plays MP3's if you want to.
