I got a newbie friend don't even have his first 50 yet and he can't see mage on his friends list but I can see him. This happens to me a lot I just force stop the game and come back that usually works but I'm on Droid he's on ipod touch what's a good task killer app for ipod touches?

Edit he don't know how to force stop the game manually on his touch that's why I suggest a task killer app.
