Hey guys, I just received my CEO premeire from marware. I have never owned an iPhone before, but have had phone that I required a sideways holster for. The CEO premiere is very sturdy and well made. The from clasps with a magnet that seems pretty strong. So long as you are not sprinting, your iPhone 4g should stay put. I put a few weights in it and bent over to see if it would hold and it did. Overall it is very nice and is made of a glossy leather as opposed to a muted wallet kind of leather. Looks very nice and has a good feel to the inside lining. I would highly suggest this case to anybody searching for a sideways holster for their phone.
