I've set my iPhone to manage my music manually and it's not set to sync my apps. However, when I try to drag an app on to my phone, it doesn't transfer it and just displays the following icon. Does anyone know why this may be the case and how to solve this problem? I don't know whether this is relevant but I'll mention it just incase it might have caused the problem. My iPhone was manually synced to my iTunes and I've just recently formatted my laptop. Thanks in advance.
