I've never tried using Tune in Radio with Get Running, so I can't be of much help there. Maybe try a different music app? I've never had trouble with Pandora, and use it for all my runs.
I'm a TuneIn Radio user too. I just tried this on my iPhone 3GS, running iOS 5.1, and it seems to work okay for me. The radio carries on playing when I fire up Get Running. I'm using the latest version of both apps.
If you ask a new question on our Get Satisfaction page, or just drop a line to getrunning@splendid-things.co.uk, that will get you through to Benjohn, who wrote the app and will be better at figuring out what's going on than I am
Hopefully response times should be pretty quick, but do bear in mind that Benjohn and his wife had a baby yesterday, so he can't devote quite as much time to support as he usually would!
