With the iPhone launch date coming up quick (here in about four weeks) you'll need to start looking for a case. Since the iPhone is going for a bit cheaper than the first gen version you're likely to have a bit more cash flow to get a nicer case.
The Dior case is simple, but with the calf leather it is definitely a luxury item. However, I have a small problem with paying more for the case than I paid for the gadget.
If you are itching for the absolute perfect case to compliment your iPhone though, then this is definitely the way to go. The case is being sold for $450.
