Hi neile457,
At first I thought it didn't. I should have followed John Clark when he suggested that I should insert my BB facing towards me (from another thread where I posted this picture).
So to answer, yes it does work with extended battery. I will have to say that this case is sooooo sturdy, it is crazy not to purchase one at this price. RIM's product description says Leather Holster with Swivel Belt Clip. A few of my customers who purchased this loved it and one complained about not being "Leather". All I can say is I go with what the manufacturer label it with. And yes, it does swivel
Anyway, see the photos below to see this case up close. I own two of this holster. One that I crop the flap off, for the Curve with Skin on (I used this for my Curve) and the other one as shown in the following photos.
Get it before July 4th, co'z this special price won't be available after the holidays.
