Just when you thought it couldn't get any better, we've now released Day-n-Night 4.0.1!

The images are now more detailed, so you can zoom in even closer! In fact, I can almost see my house from here (OK, not really, but it's still close enough that you can't see the entire US any more on the iPhone at the highest zoom level).

4.0 had a small bug that prevented it running on IOS 3.0 and 3.1 devices, plus there were a couple of things that were finished slightly after 4.0 was sent to the AppStore, all of which have been fixed in the 4.0.1 version.
