I upgraded my ip4s to ios6 and it automatically downloaded Passbook on my phone for me. When I click on the app, it opens and shows 4 categories and then the bottom of the screen, it has a link to App Store. I click it and it appears to be opening iTunes and here's my question/problem. When I click it, a message comes up saying that "cannot connect to iTunes Store" but if I close out of the app and try to open iTunes through the app on the phone, it opens fine. Is anybody experiencing this or know what is going on? If so, please help. The weird thing is, when I try looking up Passbook as an app in the App and iTunes store, nothing shows up so I'm wondering if it's just fully up and running yet.
