The Week in iPhone Cases: Say cheese

One of the items in this week’s roundup of new iPhone cases is all corners, while another teaches you how we Italians say cheese. If minimalism and multilingual knowledge aren’t what you want wrapped around your iPhone, we also have some products that bring together materials from classic leather to the latest plastics.
