Lately I haven't been able to play Pandora in the background and play games, browse safari, etc. Is there something that I switched for Pandora not to be able to multitask? Edit: Ok I noticed so far this is with Pandora.. I know their iOS4 update was supposed to support multitasking and playing in the background, the fact that I've done it before. But iheartradio plays fine.. Anyone, ideas?
