Hey! I'm currently using a iPhone 4 on iOS 4.0. Prior to the jailbreak, Skype wasn't being a cause of nuisance and running in the background. However, after the jailbreak, it doesn't seem to do so anymore. I even tried to make a call and the moment I clicked the menu button, he applicationt just quit. I simply fail to understand the reason for it behaving this way. I hope someone could be kind enough to help me on this. Thanks Mak PS: I also deleted the app and reinstalled it again. It still exhibits the same behavior.
