Is an iPhone a specialty product or a shopping product?

I'm studying for a test and I need examples of a convenience product, unsought product, shopping product and specialty.

Those terms are very specific to the context of your coursework. Just a words, they are not mutually exclusive terms. A cell phone is a speciality item that is convenient, not necessarily sought after, and very convenient. You need to ask your teacher what theses terms mean if it is not clear to you.

Shopping product.
