Like roadster, I came across some "registration-only" channels, though I didn't pursue the matter. That's kind of a drag, I'd rather not see those listed, though I've come across the same problem (and a few dead links in general) in other apps, including (IIRC) iTune's radio station presets.

It's a real bummer you can't run in the background, but obviously, that's on apple.

I appreciate that you're sticking to the rules for MP3 feeds only, there's plenty to choose from and that's a good open format, Real and WMA are a pain and not technically supported and people should be complaining to the stations to broadcast in an open format, not to you guys, how is Real even still in business? I'd rather have an app that works reliably than one that sorta-maybe plays other formats sometimes, or maybe crashes instead.

My only real complaint is that the description on the App Store claims it works on the Edge network, and in my experience, it really doesn't at all. It's understandable that Edge can't handle the data, but the app store description implies that it does. Maybe it works better for others, but even with full bars on Edge, I get nothing.

Otherwise, it's really a great product, great, simple interface, good sound, and it works great on 3G and WiFi. Nice job.
