I think I have written about DMD - (Dermander) before, but if you haven't heard of them before, DMD is a panorama app. It may seem redundant with iOS 6 having a native app, but I know quite a few people holding off upgrading, plus the app is now free for a time.
This is an excellent app that takes remarkable panoramas. Once you finish taking the photo, you can upload directly to Facebook, Twitter, email or to DMD's cloud service. You can see a finished product on my Facebook page of Newport, VT.
