"I upgraded storage for my iPhone, it’s a whole lot more than I need for my phone. How can I share this with my iPad?: I upgraded storage for my iPhone, I thought I’d be able to use it for both my iPhone and iPad. That doesn’t seem to be the case. It’s much to much for my iPhone alone. How can I share it with both devices?"
