Two Q Cases that work with Ext Battery & Covers What case works with the extended battery and Q Cover, is one of the most common questions posted on the forum. I found two cases at AT&T that work great for a Q with an extended 2100 battery and the Seidio rubberized or clear cases. Both ar $30 and in stock at most AT&T stores. I have enclosed some pictures of the cases. The first one is the Cingular Heavy Duty Carrying Case PDA. It is made of a canvas material and has a swiveling belt clip, that locks onto your belt. Once this case is on your belt, it is not coming off. The case has plenty of pockets including one for your bluetooth headset and a business card holder. This case will also hold a Q with the 3200 Battery. The second is the AT&T Carrying Case Compatible with Palm Treo 650, 680,& 750 Cingular 8125 & AT&T 8525. This is your tradional leather case that flips open from the top. The Q fits in it on its side. But is easy to access and remove.
