Hi, I am trying to figure out if it is possible to run an app, like radio app or facebook messaging, in the background while I type emails or something? I know there's backgrounder if I jailbreak my ipod, but I am afraid of jailbreaking it. I don't know if it will ruin it or i won't be able to upload things. Anyway, after the 3.0 update, is it possible to run stuff in the background? Thanks.
