I just upgraded from an iPhone 4S to an iPhone 5s.
Everything has worked fine on the iPhone 5s. The iPhone 4s still has Internet on WiFi, but of course, no phone service anymore. The problem is when I try to update apps, or order more, on the iPhone 4S I'm not able to connect to the iTunes store.
1. What do I have to do to do this? Open a separate account?
2. And I going to have to pay for my apps all over again on the iPhone 4S?
3. Should I avoid upgrading the 4s to iOS 7.x.x, as being requested?
