I went on holiday Thursday, and came back Tuesday to it in my mail box. Guess that August 27th shipment / September first arrival was a little off. Thanks Apple.
I have a cheap RocketFish leather sleeve that I used for my first iPhone after I had gone through many hated cases. The sleeve is still kicking a year later - albeit some of the trim peeling.
I think since my iPhone 4 fits rather loosely inside, it may just allow enough room for my iPhone to sport a Bumper, as well as live in the sleeve, preventing lint from gathering in the speakers & ports while in my pocket.
