Audiopress for iPhone is an amazing little app that will let you aggregate all of your podcasts, live radio, and pretty much any news audio into one easy to use app. It also allows for background audio so you can start playing a podcast within the app, close it out, and continue browsing or doing whatever you'd like while it streams in the background. Podcasts can quickly start taking up a lot of space on your device if you're bad about deleting them (which I am), so streaming them may be a much better option for those of you who'd like to save space on your device.

Just like you can create categories for your RSS feeds, you can create playlists within Audiopress. If you want your tech streams separate, you can create one for that and another for business or whatever other categories that interest you. One feature I particularly liked is when you go to listen to a podcast, it also shows you a list of previous podcasts from that feed.

You can also choose to search categories within Audiopress and find new podcasts and radio streams to listen to. I found a couple that looked interesting to me that I've become a regular listener. Before Audiopress, I'm not sure I would have ever taken the time to dig through iTunes or online radio streams to find more podcasts. So for those of you looking for something to get you more into podcasting or if you need help finding more content to listen to, this may be a good choice for you.

The app also supports Facebook integration, so if you've got a Facebook account, you can skip the sign-up and just link your Facebook account instead.
