My first post and I hope it's a helpful one. Pandora radio came out with an update recently and when I updated, the icons and the radio itself would make the HTC Hero reboot itself. Best thing to do is to delete it completely from your phone and then go and redownload it and it'll work fine. I also find that doing it this way made the radio work faster. I also had that same problem with Slacker and had the same solution for it as well.
