Psh my Best Buy still has iPhones available for release day pickup so they should have cases if nothing else.
Im not that concerned, I just like to have it in my hand BEFORE the phones arrive. (I'm not that patient also..lol)
I'll find one before Friday, I'll try Thursday night..if no luck then I just may go out Friday morning and pick one up, I expect stores will have them. I RATHER use Best Buy since I do have a store credit and a $10 off coupon that is about to expire.
