While we are waiting for TuneIn, I found that the app WP8 Radio works with tunein feeds. So it seems that if the station is in TuneIn, you can listen with this app instead.
Not as good as TuneIn, but you can at least listen to your stations.
I want to Know if we going to get a good update for tuneIn in windows phone 8, coz I've been having a lot of issues with the current version, I appreciate if I get an information from u guys. Thanks
