I have a a iPhone 4 which my boyfriend gave to me on our anniversary. I really love this piece of gadget. So I went to a store to buy a good cell phone case for the iPhone 4. They had very few pieces to choose from. When I asked the salesman said that only a few authentic case are manufactured. I know he is lying because a friend of mine who has the same phone uses a very trendy phone case. I would love to get one too. Could anyone give me links where I can shop online from variety of designs. Also please explain the payment options.
