Just bought and received one of these: http://cgi.ebay.com/ws/eBayISAPI.dll...758342145&rd=1
(linked to a closed auction on purpose...I have nothing to do with the seller other than being a paying customer)
and I thought i'd let you all know that it is a very nice case. Probably one of the best options i've found for the 7100g until RIM starts shippng the new cases from their web store. My only complaint is that you cannot remove the belt clip. However, having the attached clip makes the case thinner than one with a detachable clip. The clip does rotate as well. Sleep mode also works fine.
Now if I could just find a bluetooth headset that charges via mini-usb....
