I am deciding on what case I should put on my iPhone. Right now I have a clear one on the iPhone, but thinking about putting my black Apple Leather Case on the phone. Clients handle the phone for signature capture, so even the impression the clients get signing on my phone actually matters as well. I am no C level executive, but I do want something that exudes professionalism. The clear case has a lot of scuffs in the clear plsatic, and such, so I am wondering if I should put on the Apple leather case. What do you guys recommend?
