These issues are obviously post-IOS7 upgrade. With an iPhone4, I cannot backup to iCloud, the iCloud usage data is not displayed, and I keep sending photo stream invites, but they go nowhere and are not being processed IF they are received. With an iPhone5, every single time I go into my VM and hit 'Greetings', it freezes. If I do get in and try to listen or change my greeting (this is from the app, NOT calling in), it freezes on that screen for quite a while, and I cannot change it from the app. The iPhone4 issues are more frustrating.
